Numerical Simulation of incompressible flow has been performed on the ABU CAR 11 model moving at a speed of 40m/s. Solid Works was used to create the 3D CAD model of the car. ANSYS Fluent, the computational fluid dynamics software was used to perform the computation. All the analysis have been carried out computationally in the CFD software ANSYS Fluent 15 and the CAD modeling in Solid Works 2014 .The analysis was performed to study the flow behavior of air over the car body. The final values of the coefficients of drag, lift and momentum were found to be 3.41e-01, 3.55e-01,-5.47e-01 respectively. The analysis also included the studies of contours of pressure and velocity that impact the car body and it was found the drag could be reduced by streamlining the car body, creating perforations in the front of the car and introducing a diffuser.
