Abstract

The flow around Ahmed car body is studied for a 35° slant angle case and 25° slant angle case. For the steady 35° case, RANS modelling have shown good results but is not efficient in the 25° configuration, beeing unable to capture the detachment of the flow over the slant of the body. Then, DES and DDES modelling are performed on the 25° configuration showing better results.
