Presentation Transcript

  1. GWU BME FellowshipFlow Over the Human Hand Mentor: Dr. Rajat Mittal Presenter: Ryan Kelly

  2. Computational Fluid Dynamics • Computer Simulation of Physical Flow • Our Case: Iterative Solution of the Navier-Stokes Equations • No closed form solution • Requires Iterative Solution

  3. Hand Model: 4 Positions

  4. Meshed Model CFD Grid I • Non-uniform cartesian grid • Concentrated resolution on the fingers • 120x100x100=1.2million units • Finer resolution -> better results

  5. Meshed Model and CFD Grid II

  6. 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

  7. Pressure Distribution: Position 1

  8. Pressure Distribution: Position 1

  9. Pressure Distribution: Position 1

  10. Pressure Distribution: Position 1

  11. Pressure Distribution: Position 1

  12. Streamtraces

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