Chair’s Message
by James A. Liburdy, Ph.D.
Dear FED Members,I am pleased to be writing to all
of the Fluids Engineering Divisionmembers to report on some
newand exciting activities within thedivision. Our goal is to
helpimprove member participation bymaking it a rewarding and
produc-tive part of your professional activi-ties. Currently the
FED has approx-
imately 3500 members with another 4200 identified as sec-ondary
division members. We also would like to continue toreach out to
potentially new members to broaden out impact,to become the premier
professional society for those workingin the broad areas of fluid
mechanics. To this end we encour-age your comments and ideas as we
move forward.
This past summer we had a rather unique event, a collocat-ed
conference with the Heat Transfer Division, the AdvancedEnergy
Division, and the Nanotechnology Institute, located inJacksonville,
FL. The meeting was organized to allow partici-pants to attend
sessions sponsored by each division, andpapers from each conference
were available for all who regis-tered for any of the individual
conferences. This event broughttogether people working in diverse
yet highly overlappingareas and hopefully spawned many contacts and
potential col-laborations for the future. The conference attracted
over 750paid attendees with a truly international flair. Each
conferencehad two plenary speakers, for a total of eight. For FED
Dr.William K. George of Chalmers University was awarded theFreeman
Scholar and presented a lecture on the effects of ini-tial and
upstream conditions on turbulence shear flows, andStuart Jessup
provided an historical perspective of Navalpropulsor design.
The FED is an active participant in the ASME IMECE con-ference
held each November, and last year, in Boston, IMECE2008 was no
exception. At Boston, FED organized twelve dif-ferent symposia or
fora. Since this conference is organizedinto major Tracks, FED
participated in seven different tracks,ranging from Heat Transfer,
Fluid Flows and Thermal Systems,to Energy Systems, Emerging
Technologies and others. The
more technically oriented IMECE, compared with the past,includes
a wide range of technical events and again provides agreat
opportunity for those involved in fluid mechanics toengage with
other disciplines. In addition, IMECE is whereFED holds its Young
Engineer Paper Contest, which has beenspearheaded by Dr. Terry Beck
over the last several years.This has turned into a truly
international event, with competi-tors from around the global
coming to participate. This con-test is based on submitted papers
by undergraduate or earlygraduate students. The papers can be part
of a team projector have single authors. Typically six papers are
invited to
The Fluids Engineering Division is involved in all areas of
fluid mechanics,encompassing both fundamental as well as
applications

attend IMECE and present their work,with final judging based on
both the writ-ten and oral presentations, and awardsare presented
at the FED Reception.Some travel support is available. Weencourage
all students to consider par-ticipating in this event, the
deadlinesclosely coincide with IMECE due dates.
The next FED Summer meeting isscheduled to take place August
2-5,2009 in Vail Colorado. Dr. Joel Park isthe General Chair and
Dr. Mo Hosni isthe Technical Chair for the conference.At the time
of writing this report over500 abstracts have been submitted andit
looks to be a great conference in awonderful place. Beginning with
thisconference a new format will be imple-mented for the plenary
speakers. EachTechnical Committee now identifies aplenary speaker
that is closely alignedwith the topical coverage of the techni-cal
sessions being organized by theircommittee. The goal is to provide
a
more focused forum that includes recog-nized experts in specific
fields during theconference. We anticipate this new for-mat will
attract recognized worldrenowned speakers and expand theoverall
participation of the conference.The plenary speakers selected for
theFEDSM 2009 in Vail are: Drs. RonaldAdrian (Arizona State),
Clayton Crowe(Washington State), Willian Oberkampf(Sandia Lab.),
Darius Modarress (Measurement Science Enterprise) and
PhillippeSpalart (Boeing), with Ron Adrian being selected as this
yearsFluids Engineering Award winner. Evidence that this seems to
be a positive change in the format of theSummer Meeting is the
large number of submitted abstracts. Also, there will be a student
poster competition with cash award at Vail. I invite all to visit
the conference web site at
http://www.asmeconferences.org/fedsm09/
In closing I want to invite all to be
active participants in the Fluids Engineering Division. New
programscontinue to emerge and we want to beresponsive to members’
needs and their new ideas. If planning to attendeither the Summer
Meeting or IMECEplease plan to attend one of our sixTechnical
Committees, all are welcome.Come hear what is being planned forthe
future and participate as much astime and energy will allow.
Alternative-ly, you are welcome to contact me orone of the
Technical Committee Chairs, to discuss how to becomeinvolved.

Fluid Measurement and Instrumentation Technical Committee
Theodore (Ted) J. Heindel,Ph.D., FMITC Chair
The Fluids Measurementand InstrumentationTechnical
Committee(FMITC) is the ASME Flu-ids Engineering Divisioncommittee
devoted tomeasurement techniquesand their application to
fluid flows. The scope of the committee’sgoals include both
experimental techniquedevelopment and application in academiaand
industry. The primary activity of theFMITC includes development and
organiza-tion of technical sessions at the FluidsEngineering
Division summer meetings andthe fall IMECE meetings. Since fluid
meas-urements are common to all experimental-ist, the FMITC also
collaborates with otherFED technical committees in
co-sponsoringtechnical sessions. The committee’s mem-bership
represents a broad spectrum ofbackgrounds, including industry,
govern-ment laboratories, and academia. Thetypes of measurements
and instrumenta-tion include those applicable to subsonicand
supersonic flows, multiphase flows,large-scale flows, microfluidic
flows, andmany others. The FMITC goal is to be atthe forefront of
new measurement tech-niques and to provide a forum to
exchangemeasurement and instrumentation ideas,developments, and
applications.
The FMITC meets at the ASME FEDSummer Meeting and at the ASME
IMECEmeeting. Non-members from students toseasoned professionals
are encouraged toattend these meetings, which areannounced in the
respective conferenceprogram. We are continually looking fornew
members to assist in, as well asdevelop new, technical sessions
address-ing measurement and instrumentationissues. We also
encourage those fromother ASME divisions and technical com-mittees
to attend to develop collaborativetechnical sessions which extend
the appli-cations of fluid flow measurement andinstrumentation to
other disciplines, suchas heat transfer, bioengineering,
energysystems, etc. Examples of recent technicalsessions sponsored
or co-sponsored bythe FMITC include: Forum on Fluid Mea-surement
Uncertainty Application, Panelon CFD/EFD Choice – A Dilemma
forIndustries, Symposium on Non-InvasiveMeasurements in Single and
MultiphaseFlow, Forum on Fluid Measurements andInstrumentation, and
Forum on Automo-tive Flows.
If you have any questions or sugges-tions for the FMITC, please

vice-chair, Pavlos Vlachos at [email protected]. �
Computational Fluid DynamicsTechnical Committee (CFDTC)
Richard W. Johnson, PEChair, CFDTC, IdahoNational Laboratory
This summer at the2009 FEDSM in Vail,Colorado, the CFDTC
willhost its historically impor-tant symposia on newCFD algorithms,
new andtraditional turbulence
modeling approaches, fluid-structure inter-action and
flow-induced noise and generalCFD applications. In addition, CFDTC
joinsFMTC in hosting a symposium on verifica-tion and validation in
CFD. In conjunctionwith the V&V symposium, the CFDTC hasinvited
Dr. Bill Oberkampf to present a ple-nary talk at the FEDSM
addressing thisvery issue.
While we may view the historical areasof CFD interest as being
the most fun towork with, as engineers, we must alsoengage
ourselves in the perhaps not soexciting task of qualifying our CFD
simu-lations for the benefit of the recipient oruser of those
calculations. We need to ver-ify our CFD coding, verify our
calculationsand validate our calculations. We all knowthat anybody
who can run a computerapplication and click on options can pro-duce
a “CFD simulation.” But how good isthat simulation? Has it been
processedthrough the various procedures that weknow to be basic to
its acceptability? Arewe conversant with the terminology thathas
come to be generally accepted in theV&V community. How about
our manage-ment? Do they know what is required toqualify a CFD
calculation?
There are a number of subjects relatingto the practice of
V&V that can actually bequite deep and may strain our
intellectualcapacities. For instance, we would like tobe able to
quantify the numerical uncertain-ty of the calculation. How do we
do that? Isthere more than one way? Do we have touse 2 or more
grids to do it? Also, there isa need for a quality database of
experimen-tal data that can be accessed by CFD prac-titioners whose
contents is comprised ofvalidation data sets that are complete
andalso have a qualification pedigree, especial-ly a good
uncertainty analysis. When wethen attempt to use data from the
valida-tion database, we need to do better thanprovide the usual
“viewgraph” norm com-
parison. That is, there should be one ormore procedures that
produce some kindof numerical metric such as a confidenceinterval
that quantifies the simulation ver-sus the data. Many of these
procedures arestill subjects of research and improvement.You should
become acquainted with themand their genesis.
If we want the (engineering) world toaccept our CFD magic as
reliable approxi-mations of reality, we have to provide thepedigree
or list of quality assessments thathave been performed to qualify
it. We mustbe conversant with the terminology and theprocedures
that comprise it. In manyregards, CFD is a mature engineering
sci-ence, though we hope to be able to contin-ually improve on
existing techniques. Butwe must also certify our work to our
cus-tomers so that its full power can be takenadvantage of and
appreciated.
We invite all to attend the plenary talkby Dr. Oberkampf who is
an acknowledgedexpert in V&V and has served on a numberof task
forces to develop and codify V&Vpractices and procedures. He is
also in theprocess of co-authoring a book on V&Vpractices. We
also invite you to participatein future V&V symposia we hope to
hold atfuture FED summer meetings. �
Fluid Applications and SystemsTechnical Committee (FASTC)
S. A. Sherif, Ph.D., Chair& D. Keith Walters, Ph.D.,
Vice-ChairFASTC, Fluids Engineering Division
The Fluids Applications and SystemsTechnical Committee (FASTC)
continueto promote the advancement and dissemi-nation of fluids
engineering research andtechnologies in several wide-ranging
single-and multi-disciplinary topic areas. Theseinclude such
traditional disciplines as fluidpower systems, turbomachinery,
automo-tive flows, and industrial and environmentalfluid mechanics,
and can include less tradi-tional topics such as biological and
bio-medical systems, chemical processing, orfluid vibrations and
acoustics. The primaryfunction of the committee is to coordinateand
organize research symposia at twomajor venues for fluids
engineering—theannual ASME Fluids Engineering DivisionSummer
Meeting (FEDSM) and the ASMEInternational Mechanical Engineering
Con-gress and Exposition (IMECE)—as well asother FED sponsored
meetings and events.Researchers and engineers from
academia,industry and government are encouragedto meet and exchange
information on theseand other topics through their participationin
FASTC.

Fluid Mechanics Technical Committee (FMTC)
Francine Battaglia, Chair& Javid Bayandor, Vice-Chair
The Fluid MechanicsTechnical Committee isdedicated to
organizingand promoting technicalactivities within ASMErelated to
fluid mechan-ics. Members of the
FMTC volunteer their serves to develop,organize and promote
symposia and paneldiscussions on fundamental and contem-porary
topics relevant to the researchcommunity. Often, these platforms
areheld twice per year at the InternationalMechanical Engineering
Congress &Exposition (IMECE) and Fluids Engineer-ing Division
(FED) Summer Meeting.
The FMTC is pleased to announce thatProf. Mory Gharib, the Hans
W. LiepmannProfessor of Aeronautics and Professor of Bioengineering
at Caltech, will be a plenary speaker at the 2009 Fluids
Engineering Division Summer Meeting to be held in Vail, CO this
August. For further information about the meeting and plenary
speakers, please visitwww.asmeconferences.org/FEDSM09/
To coincide with the annual confer-ences, the FMTC holds a
business meet-ing at the IMECE and FED events. Elec-tion of the
FMTC officers was held at the2008 FED Summer Meeting in
Jack-sonville, FL, after which the officers servea two-year term
(2008-2010). During thebusiness meeting held at the 2008 IMECEin
Boston, MA, the FMTC memberspassed a motion to allow only two
formattypes when authors submit abstracts formeeting presentations.
Beginning withthe 2009 IMECE, authors will have theoption of either
submitting a full technicalpaper for presentation, which will also
bereviewed and published in the proceed-ings, or giving a
presentation only(abstract but no paper). We hope theseoptions will
promote and encourage moreauthor participation in the sessions
spon-sored by the FMTC.
During the last few years, we havewatched the membership of the
FMTCgrow to include involvement from gradu-ate students,
postdoctoral research associ-ates, and junior faculty members.
Theinfusion of new members helps the FMTCsustain our professional
activities. Withoutthe support and dedication of the FMTCmembers,
we would not be able to offerthe variety of technical sessions held
atthe annual conferences.

IntroductionUnwanted dispersed matter (dust or
droplets) in industrial vapor streams is acommon problem.
Cyclones, havingrelatively low costs of construction andoperation,
have been used since the late1800s to separate these phases.
Parti-cle-laden gas enters through an inlet,swirls in a free vortex
around the bulk ofthe unit, and proceeds into the forcedvortex
before exiting the top of the unit.Particle-rich gas leaves the
bottom intoa dust bin or other collection system. Inthe present
work a Lappel cyclone cou-pled with an annular ejector is used
toremove polyethylene dust from a densegas stream. The goal is to
optimize thesystem within strict geometric and oper-ating
constraints.
ModelFigure 1 shows the overall layout of
the present work. A multitude of meshblocks is used to minimize
mesh spacingin areas of high gradients, cell skewness,cell aspect
ratio, and cell centroid shifts.The grid size ranged from 570,000
to740,000 cells, the vast majority of whichare hexahedra.
Two-equation turbulencemodels cannot account for couplingamong the
Reynolds-stress tensor com-ponents, concave surface
turbulenceenhancement, or counter gradient diffu-sion physics;
therefore, a differentialReynolds Stress Model (RSM) solutionwill
be sought. Mach numbers are signif-icant in the present study, so
compress-ibility, viscous heating, pressure work,and the kinetic
energy terms wereresolved. The dispersed phase isapproached using a
Lagrangian stochas-tic discrete random walk (DRW) method[1]. A
commercially available pressure-based, 64-bit, finite volume,
double pre-cision code, Fluent 6.3.26, was used tosolve the
equations governing momen-tum, heat, and turbulence in both
phasesin space and time. The convective termsof the momentum
equations were dis-cretized using a QUICK scheme. Atimestep size
and sub-iteration countwere chosen such that RMS
residual“flattening” (continuity of order 10-5)was achieved and the
instantaneousmass imbalances were less than +/- 1%.Each run
proceeded in two stages: 1)
development of statistically stationary(quasi-steady) flow and
2) time-aver-aged data collection. To help decidewhat exactly
represents “enough” timefor the first stage, 22 values, such as
tur-bulence kinetic energy and Mach num-ber, were monitored during
the runs.
Flow FeaturesFigure 2 offers typical instantaneous
contours of tangential velocity, tempera-ture, and dust
concentration. Anexpected strong swirling motion is seenwith an
asymmetric approach to thelower outlet [2]. Hot vapor is fed to
theinlet, and hot motive fluid is fed to theejector. Gas expan-sion
lowers the tem-perature in the cen-ter of the cyclone.The clean
(upper)outlet is relativelywarm and is likely acombined effect
ofstrong radial turbu-lent thermal diffu-sion near the vortexfinder
[3] andbypassing of thefeed flow to the vor-tex finder. The
par-ticle concentrationcontours show anexpected increasein
concentrationnear the walls of thecyclone and vortex
finder. There are also interior lobes ofhigher concentration
dropping down tothe lower part of the straight cyclonesection, and
some particles (entrain-ment) are seen making their way backup the
center in the return vortex.Notice also the relatively high
concen-tration of particles just under the vortexfinder. Bypassing
appears to be thedominant mechanism for particle carry-over. The
particle concentration contourshapes, especially the interior
“bands”,change dramatically in time. The quasi-steady behavior is
exemplified in Figure3, showing a typical time series plot ofthe
overall system separation efficiency.

Figure 4a shows instantaneousLagrangian particle tracks released
fromthe cyclone inlet colored by residencetime. Particle
concentration helical stri-ations are seen forming in the
cyclone([2], [4]). There is evidence of strongbypassing of the
particles under the vor-tex finder. The shades of blue (low
resi-dence time) proceeding vertically out ofthe clean top indicate
a short period oftime that particles are in the unit.Bypassing is
further explored in Figure4b. Here, the continuous phase istraced
by residence time moving inreverse from the clean outlet. Shades
ofblue (low residence time) are seen invarious positions in the
inlet. Anotherinteresting feature is the particles caughtin the
secondary flows shown in red(long times) near the cyclone roof
dis-cussed in [2]. Typical instantaneoustangential velocity
contours on an ejec-tor midplane are shown in Figure 5.Three
uncorrelated time steps have beensampled to show the unsteady
nature ofthe flow. Rings of helical flow are shedas the vorticity
of the swirling cycloneflow re-orients upon meeting the high-speed
ejector motive steam. It can be
seen that the effects of the cyclone arechaotically felt deep in
the ejector. Itwas found that the state of the flow exit-ing the
cyclone bottom affected themotive feed pressure balance. The
pres-sure balance controls the ejectorthroughput. In turn, the
amount ofmaterial ejected impacts the solids car-ryover rate. The
two units could, there-fore, not be separated computationally.
ConclusionsThe complete work can be found in
[5]. Six geometric configurations forimproving the solids
collection efficiencyof a joint cyclone separator / ejectorhave
been evaluated using an unsteady,compressible DRW with RSM
approachin a commercial code, Fluent 6.3.26.Significant effort was
placed on ensuringa converged solution with statisticallysound data
collection and time-averag-ing. It was found that an extended
con-vergent vortex finder had the greatestimprovement in particle
collection, whilethe pressure drop increased markedly asexpected.
Two sizes of simple disk-shaped vortex breakers showed
noimprovement, while an extended vortexfinder with a fixed diameter
showed adecline in performance. A dust bin
showed a very slight improvement, butthe dust bin was a
non-ideal design dic-tated by process space limitations.
Allparticle collection directional changeswere marginal. Solids
collection did notnecessarily correlate with tangential flowin the
downpipe or ejector throughput.More work is planned to evaluate
vari-ants of these designs and others. Inaddition to six geometry
evaluations,four numerical effects were
considered:pressure-velocity coupling, pressure dis-cretization,
RSM pressure strain formula-tion, and wall reflection. Minor
effectswere found by changing from the linearto quadratic
formulation. Almost noeffect was seen when the pressure-velocity
relations was handled in a cou-pled or SIMPLE approach. Very
largechanges were seen by choices for pres-sure discretization and
the inclusion ofwall reflection terms. It was concludedthat a
PRESTO! scheme and the linearpressure strain approach with no
wallreflection are the most accurate and effi-cient approaches.

Unified Two-Phase CFD Modeling of Boiling, Cavitation, and
Bubble CollapseRay A. Berrya, Richard Saurelb, Fabien Petitpasb
Keyissues in nuclear reactor safetyand optimization rely on
in-depthunderstanding of basic two-phase flowphenomena with heat
transfer and phasechange. Among these issues, convectiveboiling
under normal and elevated pres-sure conditions is one of the most
chal-lenging situations. Our inability to accu-rately predict heat
transfer and associat-ed boiling fluid topology transitions
fortwo-phase flows under nuclear reactorflow conditions and fuel
bundle geome-tries results in increased safety marginswhich impedes
development of new fueldesigns. With the advent of new genera-tion
codes and the increase of availablecomputational power, it is
believed (asevidenced at the recent international“Two-Phase
Convective Boiling FlowModelling” workshop [1]) that
significantprogress can be made by using special-ized computational
fluid dynamics(CFD) codes, thus leading to a drasticreduction in
development costs. InEurope, and especially France, CEA,EDF, AREVA
and IRSN have launched,among several projects covering a
broadspectrum of space and time scales, theNEPTUNE [2] project,
aimed at provid-ing computational tools describing two-phase flow
and heat transfer that arevalidated in the parameter range
ofindustrial applications. In the UnitedStates no such unified
effort exists; how-ever, it seems necessary to promote
col-laborative research on this subject at thewidest scale. A
collaborative effortbetween the Multiphysics MethodsGroup at Idaho
National Laboratory(INL) and the SMASH Team at ÉcolePolytechnique
Universitaire de Marseillehas recently begun to pursue theseissues
through development of a unifiedapproach [3]. This short research
notehighlights one component of the broaderdevelopmental effort
[3].
The purpose of this research is todevelop the foundations needed
tosimultaneously solve both fluid dynamicinterface problems and
multiphase mix-tures problems arising from boiling, cavi-tation,
and bubble collapse in light waterreactor systems. The two-phase
flow
phenomena occurring in light waternuclear reactors includes,
especially withdeparture from nucleate boiling (DNB)and film
boiling instability (boiling crisis),coolant phase changes and
multiple flowregimes that directly influence coolantinteraction
with the fuel elements andassemblies, ultimately affecting
reactorperformance. Because of the inherentcoupling, an
understanding of these phe-monena, along with subcooled boilingand
bubble collapse, is also key to gain-ing an understanding of crud
depostionin these systems. Our goal is to provideunified models
giving highly resolvedsolution details where necessary,
simul-taneously with lower resolution, large-scale vessel/component
solutions. Thiswill be accomplished through the develo-ment of a
well-posed, multiscale methodthat (1) resolves interfaces for
largerbubbles with single velocity, single pres-sure treatment in a
DNS-like (directnumerical simulation) manner using afine
computational mesh, and (2) aver-ages (or homogenizes) the
two-phaseflow field for smaller bubbles, yielding atwo-velocity
two-pressure treatment,using a courser computational mesh.
Multiphase formulations have beendeveloped to provide the
ability to solveproblems involving both heterogeneousmixtures of
materials and interfacialflows involving compressibility withphase
transition. In particular, for theDNS of interfacial flows which
are ofprime importance for nuclear reactordesign optimization and
safety analysis,the aim is to compute the critical heatflux
conditions that involve a competi-tion between bubble growth,
surface ten-sion, contact angle effects, and heat andmass transfers
at interfaces. Contrary tothe approach developed by
otherresearchers, such as sharp interfacetracking methods, our
approachembraces a general model that accountsfor complete
thermodynamics in bothphases. Because of the inherent weak-nesses
of sharp interface methods forDNS-like simulations, most notably
theirinability to dynamically create interfacesand to solve
interfaces separating pure
media and mixtures, we focused on adiffuse interface method
(DIM) whichdoes not exhibit these weaknesses. DIMconsiders
interfaces as numerically dif-fused zones corresponding to
artificialmixtures created by numerical diffusion.The determination
of thermodynamicflow variables in these zones is achievedon the
basis of multiphase flow theory.The challenge is to derive
physically,mathematically, and numerically consis-tent
thermodynamic relations for theartificial mixture. The same
solutionmethod is implemented globally in bothpure fluids and in
mixture zones. For thisresearch the numerical approximation ofthe
five-equation, two-phase flow modelof Kapila (zero-order
approximation ofthe seven-equation model with stiffrelaxation) [4],
which has shown excel-lent capabilities for numerical resolutionof
interfaces separating compressiblefluids and wave propagation in
com-pressible mixtures, was examined. Forseveral reasons, its
numerical approxi-mation poses serious difficulties. In ourwork,
these difficulties were circumvent-ed by restoring pressure
non-equilibriumeffects using a pressure non-equilibriummodel
developed in [5]. This resulted ina single velocity,
non-conservativehyperbolic model with two energy equa-tions
involving relaxation terms; it fulfillsthe equation of state and
energy conser-vation on both sides of interfaces andguarantees
correct transmission of pres-sure waves across them. This
formula-tion considerably simplifies numericalresolution by
building a simple and effi-cient method for numerical
approxima-tion of this flow model in the context ofdiffuse
interfaces. Further details of themethod and results are given in
[5].
To demonstrate the multidimensionalcapability, a two-dimensional
test,involving a Richtmyer-Meshkov instabil-itly (RMI), is
presented from [5]. The liq-uid is not pure and new interfaces
willappear during development of the insta-bility due to cavitation
effects. Theshape of the resulting interface and theentire flow
field show a non-conventionalbehavior, never computed before, as
themodel and method must deal with liq-

uid-gas interfaces and the dynam-ic appearance of gas pockets
insevere conditions. The physicaldomain is 3 m long and 1 m
high,with the left part of the computa-tional domain filled with
nearlypure water and the right part withnearly pure gas. They are
initiallyseparated by a curved interface, aportion of a circle with
0.6-mradius centered at x=1.2 m, y=0.5m. The mesh contains 900
cells inthe x-direction and 400 cells in they-direction. Both water
and gashave an initial pressure of 1atmoshere and an initial
velocityof -200 m/s (to the left). The ini-tial density of water
and gas is1000 kg/m3 and 100 kg/m3,respectively. Top, bottom, and
leftboundaries are treated as solidwalls; right boundary is open.
Bothphases are treated with the stiff-ened gas equation of state
[6];therefore, both phases areassumed compressible. The waterin the
left part contains a verysmall volume fraction of gas, 10–6,while
the gas in the right part con-tains a very small volume fractionof
water, 10–6. The initial configu-ration is shown in the
uppergraphic of Figure 1, and the mix-ture density contours at
times 0.0,1.9, 3.9, 5.8, and 7.8 ms in theother graphics of the
figure. Whenflow impacts the left wall, a right-traveling wave
propagates in thedomain through the water/gas dis-continuity. A
conventional RMIappears first. Then expansionwaves are produced as
the jetelongates. It results in expandedzones near the solid
boundarywhere gas inhomogeneities grow,producing the dynamic
appear-ance of gas pockets (white) andinterfaces. Because the
pressure isvery low in these zones, the jet’sdynamics are modifed
from theconventional RMI in pure fluids. The var-ious gas pockets
near the solid bound-ary and in the jet core are clearly visiblein
Figure 1. Relaxation terms present inthe volume fraction and energy
equa-tions are responsible for the dynamicappearance of these gas
pockets. Thiswould be very difficult to accomplishwith current
sharp interface trackingmethods.
By incorporation of interfacial surfacetension and heat and mass
transfereffects, this simple, efficient and robustmethod can be
used to resolve fundamen-tal boiling issues in a DNS-like
mannersimilar to the cavitation example above.Furthermore, the
various componentsemployed in this method are generalenough to
merit coupling with additionalcomplex physics and chemistry, e.g.
toaddress the unwanted deposit of con-
stituents dissolved in the coolant asa result of localized
boiling — the so-called crud deposition problem.
