Active procedures to control the flow past the Ahmed body with a 25° rear window
Résumé
Ahmed body with a 25 degree rear window is used to represent a simpli ed 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.
