Abstract

Based on the recent work of Stella et al. on the bidimensional (2D) flow behind a ramp [11, 10], the present paper aims at analysing the entrainment phenomenon in a three-dimensional (3D) turbulent wake downstream of a bluff-body. Numerical and experimental data of different configurations of the Ahmed body are investigated. This study is part of a framework on the aerodynamic drag reduction for ground vehicles by defining proper and realistic control laws derived from the entrainment.
