8. Venturi Analysis: Matlab Code

9. Venturi Modeling: Gambit Meshing
Initial Meshing utilizing 2007 FSAE Venturi
Tet/Hybrid HexCore meshes
2,000,000 mesh points
Volume meshing
Meshing of new Venturi designs

10. Venturi Design: Gambit Meshing
Face Mesh
Volume Mesh

11. Venturi Design: Gambit Meshing

12. Venturi Modeling: Fluent Modeling

13. Venturi Modeling: Fluent Modeling and Analysis
Imported .neu files
Geometrical tolerance modification
3-dimensional simulation
Grid as interior fluid
Can be run on Vampire
Only as an executable file
Results must still be compiled on home drive
This is not necessarily a time-saving option

14. Intake Modeling: System Methodology Decision
Bi-lateral approach
3-Dimensional Flow Visualization
1-Dimensional Analytical Modeling
Helmholtz Resonance
Could be supported by dynamometer testing after design phase is complete

15. Vanderbilt Motorsports Intake and Exhaust Project
Next Steps
Fluent Models of Venturi design
Design for new Venturi
Outline for 1-Dimensional analytical flow solutions for intake manifold
