Computational Fluid Dynamics
Computer Simulation of Physical Flow
Our Case: Iterative Solution of the Navier-Stokes Equations No closed form solution Requires Iterative Solution
Hand Model: 4 Positions
Meshed Model CFD Grid I
Non-uniform cartesian grid
Concentrated resolution on the fingers 120x100x100=1.2
million units Finer resolution ->
better results
Meshed Model and CFD Grid II
Current Results
Technical Issues Resolved System finally debugged Some initial qualitative results have
been obtained Pressure Distributions, Streamtraces
(streamlines) are of greatest significance at this time
Quantitative results forthcoming, require further analysis
Pressure Distribution: Position 1

Streamtraces
The Future
Simulate Established Flow Extract pressure, viscosity, vorticity
measurements Compute drag on the hand for each
position Publish (?)
