Determination of Coefficient of Lift And Lift Force on Sedan Car Body by Changing Different Parameters Using Open Foam

Abstract

One of the major factor that determine fuel efficiency of a ground vehicle is its aerodynamic drag. Here interest was to study the aerodynamic performance of car geometry for sedan type vehicles and by changing their different parameter Lift force were calculated by using CFD Software OpenFOAM. This study involves variation of geometrical features, such as hood angle, wind screen angle, rear angle, and corner radius. Car geometries were created in OpenFOAM itself by using blockMesh. Meshing was done by using snappyHexMesh. Total 14 sedan geometries were used.Comparison was made to find the geometry with least drag
