AERODYNAMICS STUDIES OF VARIOUS PASSENGER VEHICLES USING COMPUTATIONAL FLUID DYNAMICS (CFD)

Abstract

This research work explores the aerodynamic characteristics of various automobiles, specifically passenger vehicles like sedans, SUVs, and hatchbacks, utilizing computational fluid dynamics (CFD) simulations and performing practical experimentation using wind tunnel. Previous studies on this topic were not able to give a comparative aerodynamic analysis of different automotive body type of automobiles. The study focuses on comparing the pressure distribution on the body of each vehicle type due to aerodynamic forces to gain insights into their aerodynamic performance and will help determine the efficient aerodynamics and how it causes a reduction in drag forces when compared with a general passenger car. The primary objective is to investigate the influence of different vehicle geometries on aerodynamic performance. The findings aim to contribute valuable insights for optimizing automobile design to enhance fuel efficiency and overall performance.
