Abstract
This work proposes an efficient numerical model based on the Computational Fluid Dynamics (CFD) approach to get the flow structure around a car with a distinct height of Spoiler. The main target of the project is to show such aspects using a CFD packages. Our project is to investigate the aerodynamics characteristics of a car with rear spoiler and without rear spoiler and investigate the suitable height of the rear spoiler. Four totally different velocities are chosen for this analysis. It's found that the installation of a spoiler at the height of 371mm upper surface of the vehicle trunk. At this position, the total drags coefficient reduction of 26%
