摘要

Ahmed body with a 25° rear window is used to represent a simplified car geometry. Two- and three-dimensional simulations are performed to analyse the flow behaviour around such a vehicle. Sucking and blowing jets or slots are added on the body to control the flow. The results presented show that good drag reductions are achieved for a good choice of the active procedure.
