Abstract

The main aim of this paper is investigation of aerodynamics of passenger car, measuring drag coefficient. This work proposes an effective numerical model based on the Computational Fluid Dynamics (CFD) approach to obtain the flow structure around a passenger car with Splines and Rear Spoiler. The experimental work of the test vehicle and grid system is constructed by HYPERMESH. FLUENT which is the CFD solver & employed in the present work. In this study, numerical iterations are completed, then after aerodynamic data and detailed complicated flow structure are visualized. In the present work, model of generic passenger car has been developed in CATIA and generated the wind tunnel and applied the boundary conditions in HYPERMESH platform then after testing and simulation has been performed for the evaluation of drag coefficient for passenger car. In another case, the aerodynamics of the most suitable design of vortex generators is introduced and analyzed for the evaluation of drag coefficient for passenger car.
