Reverse Engineering

Computer Aided Design(CAD) has

become more popular, reverse

engineering has become a viable

method to create a 3D virtual model

of an existing physical part for use in

3D CAD, CAM,CAE or other

software.

The reverse-engineering process

involves measuring an object and

then reconstructing it as a 3D model

Digitization

Digitizing or digitization is the

representation of an object

image, sound, document or a

signal (usually an analog signal)

by a discrete set of its points or

samples.

Computational Fluid Dynamics or CFD is

predicting what will happen, quantitatively, in the

analysis of systems involving fluid flow, heat transfer

and associated phenomena such as chemical reactions

by means of computer based simulations.

The technique is very powerful and spreads a wide

range of industrial and non industrial applications.

What is CFD?

IC Engine

 An engine in which combustion takes

intermittent.

Our CFD analysis in IC engine by changing,

1)Various combustion volume

ratios ,

2)Ignition time,

3)fuel properties,

4)Emission Test

for both petrol engines and diesel engines heads.

Wind Tunnels

Tool which is used in aerodynamic research to study the

effect of air moving past around solid objects.

Results of wind tunnel can be validate through CFD

techniques so its called manual CFD.

Our design achievement in design of wind tunnels are

subsonic tunnels with high mach number (0.5-0.9) flow rate

at 80m/s, supersonic tunnels with storage tank with anechoic

system at mach 2.

Test section design for Industrial requirements .

Perfect Nozzle designs for Subsonic, Supersonic,&

Transonic with variable area design & analysis.

Flow over Autonomous Under water Vehicle

Autonomous Underwater Vehicles (AUV) are free

swimming marine robots that require little or no

human intervention.

AUV are used for commercial, military, research

purpose etc...

Marine propeller is one of the most challenging

problem

Turbine Blade Stress Analysis

Turbine blade is the major part in Aero Domain.

Work of turbine is to convert low pressure to high

pressure and to send hot gases to Nozzle through

Nozzle guide vanes and also to withstand High

temp gas which comes out from Combustion

chamber,

Our CFD,FEA analysis on turbine blade is at

36000 rpm with1200’C temp to choose High

temperature material like Inconel 710,720,Udinet

720,RR 1000,Li 720Ni which is suitable for all

conditions.

Fuel Cells Device which convert chemical energy of fuel

to electrical energy.

Types PEMFC(Polymer electrolyte membrane

fuel cells),SOFC(Solid oxide fuel cells),High

temp electrolysis.

Thermal engineering techniques.

The use of an interlayer is proposed for the reduction of

kinetic energy loss and the formation of intermetallic

layer at the interface.

Our analysis an explosive is done through Autodyn for

various detonators ad various metal bonging with and

without interlayer.

Roll Rate of Missile

While free flight missile generate ‘Adverse roll’

arising from manufacturing asymmetry, small

protrusion,sepration dynamics & unsteady

atmospheric conditions

This problem arise when roll rate is more than

10RPM

Our CFD analysis on missile is to analysis the roll

rate with and without canard configuration to

avoid Adverse roll when it launch from aircraft.

Underground Garage Systems or Car Park are an

innovative idea that provide a unique underground

parking solution.

This car parking system doubles vehicle storage

potential by utilizing space that we already have.

It also adds an extra layer of protection for vehicles

which can potentially lower our insurance

premiums.

Underground parking systems are a convenient and

cost effective way.

 This may be an ideal solution for a listed building

or where building restrictions are a problem.

Suggested Fan location

No Stagnation

Airflow Analysis

Airflow analysis is done to ensure the

optimum number of fans and its

locations ,so that there is no stagnation

inside the car park.

Carbon monoxide (CO) Analysis

Carbon monoxide simulation is done to ensure

the event of a CO high level (>100 PPM [Parts

Per Million] ) is avoided at short term exposure

of 30 minutes.

Fire Case Scenario

This is a post fire smoke management

system, thus in the event of fire, there is a

clear view of over 30m from any corner

of the car park to the nearest means of

escape point within 45 minutes, after the

fire starts.

From Airflow, CO and Fire conditions,

we can conclude whether the ventilation

system provided is effective or not.

Cyclone Heat Exchanger

Cyclones have been one of the oldest and most popular devices

for the removal of dispersed particles from the carrying gas flow

because of the simple design and ability to operate at high

loading.

Determining the holdup mass and the time required by the

particle to reach the bottom of the Cyclone Heat Exchanger

using CFD analysis by varying the size, mass flow rate and

position of solid particles.

Holdup mass is inversely proportional to velocity if velocity

increase holdup mass will decrease.

Aircraft Landing Gear stress Analysis

Landing gear is the most important part of

aircraft.

Many major accidents happen during landing. So

landing gear analysis is most important.

The structural analysis for landing gear is done at

various load conditions applied.
