Spoiler CFD - Updates
M&S CoE, EIEC, Pune
23rd June 2011
Model set up Wind Tunnel Testing
CAD Model used in CFD
Taurus model is used to leverage developed CFD methodology on actual car
Actual CFD Domain
Extended CFD Domain
Working fluid : Air @ std atmospheric conditions
Inlet is placed 2L distance from the leading edge & Outlet is placed at 5L distance from trailing edge of Car in order to capture wake effects properly
Mesh sensitivity Study
Drag Prediction at Different velocities
After 7M error is < 5%. 7M mesh is finalized for
drag prediction of car model without spoiler.
CFD results are > 95% agreement with test data
At high velocity more separation observed
Test and CFD Comparison
