An important aspect affecting a ground vehicle's fuel economy is its aerodynamic adrag. Thus, the goal of this research was to examine the aerodynamic/performance of automobile geometryc for a/hatchback. By adjusting various parameters, we were able to quickly determine the Drag force and Lift force using the OpenFOAM programme. In this investigation, various geometries with marginally varied characteristics such as hood, windscreen, back, and corner radius are used. Geometries for this project are produced directly in OpenFOAM using blockMesh. Using snappyHexMesh, meshing is accomplished. This study primarily uses 10 Hatchback geometries, whose varied contours are displayed at various speeds together with the determination of their coefficients of drag and lift, leading to the identification of one Hatchback shape that is optimal.

Keywords : Open FOAM, Dragd force, Lift force, blockMesh, snappyHexMesh.
