Abstract: Computational Fluid Dynamics (CFD) is the numerical techniques to solve the equations of fluid flow. CFD tool is found very useful in automobile industry ranging from system level (exterior aerodynamics, ventilation, internal combustion engines) to component level (disk brake cooling).CFD simulations are carried out by dividing the physical domain into small finite volume elements and numerically solved the governing equations that describe the behaviour of the flow. The governing equation (Navier Stokes equations) is very complex and almost impossible to solve analytically thus requires numerical techniques. In the present paper, research work in the field of “CFD analysis of aerodynamic drag reduction of automobile car ” has been reviewed
