EnSight visualization of the streamlines around a rally car example. The streamlines were generated from the predicted vortex location, thus helping to investigate the flow patterns around the vehicle. Contours on the car are of "downforce", where areas of cold color are generating downforce, while areas of hot color are generating lift.
Inlet Ground Vortex.
Image portrays a calculation of the ground vortex generated while an airplane operates on the ground at very low speed and high power settings; the CFD code OVERFLOW was used for the simulations. Image courtesy of Drs. Yoram Yadlin and Arvin Shmilovich of the Boeing Company.
