About Ahmed Body
a benchmark in vehicle aerodynamics. It has been use een used in severa n several experiments and
many numerical studies. Special attention is focused on the time averaged flow in the
near-wake and the dependence of drag and lift on the slant angle at the top rear end. wake and the dependence of drag and lift on the slant angle at the top rear end.
Wind tunnel experiments on this model show two critical slant angles: 12 5 degree and
