Abstract	The main objective of this paper is to elucidate the variation of various aerodynamic factors (drag lift) and also examine pressure variations when a body corners. This is accomplished by investigating the variation of the rear slant angle of the Ahmed body and its effect on the drag and lift coefficients through numerical simulation .To study variations in a cornering or an overtaking scenario, yaw angle is introduced in the body. The simplified vehicle geometry: Ahmed Reference Model has been used as a benchmark. Three types of slant angle categories have been chosen for the present study notch back, hatch back, square back and a comparison study has been carried out. The computational part consists of numerical simulation of the flow around the Ahmed Body employing CFD (Computational Fluid Dynamics) techniques. In numerical simulation results, pressure-based solver was utilized and the turbulence model employed was k-Epsilon realizable model with non-equilibrium wall function for near wall treatment. The designing of model used in this paper is done through the SOLIDWORKS ‘14; and CFD simulation carried out in FLUENT (ANSYS 15).
