Abstract

Performance, handling, safety, and comfort of a car are significantly affected by its aerodynamic properties. Getting high power directly from the engine is just not enough to judge the performance of the car. Aerodynamic properties must be considered for the purpose of studying the drag and stability performance of a car. In order to improve a car’s aerodynamic drag and its stability, an aerodynamic device is needed to perform such as the rear spoiler. Rear spoiler is an aerodynamic device that functions to ‘spoil’ the unfavorable air flow across the body or in the scientific explanation, to spoil the ‘laminar’ flow of the car’s aerodynamic movement in motion. This rear placing device creates an area of high pressure to replace the usual low pressure over the trunk resulting in increasing stability of the car. Basically, rear spoilers are fitted at the trunk of a sedan car for its performance but does it gives the same results if a rear spoiler were fitted in a Multi Purpose Vehicle (MPV)? Or just for the sake of styling purpose. Thus, this report is regarding the effect of rear spoiler on a MPV and the objective of this study is to investigate the aerodynamics on a MPV vehicle with rear spoiler using CFD software (ANSYS). A simple model of the MPV had been drawn using CATiA software; import it to ANSYS software and to run the aerodynamic simulation.
