In recent years, increasing use is being made of computational methods to aid in the understanding of the flow complexities around vehicles and as a result many areas of a car have been studied for numerical solution. Two simulations are made, one for the flow around an Ahmed body and the other of the flow around a simplified high speed passenger car. The former simulation of airflow over Ahmed body is investigated using Fluent in which the configurations included different rear slant angles. The aim of studying such a simplified car body is to understand the flow processes involved in drag production. Through understanding the mechanisms involved in generating drag one should be able to design a car to minimize drag and therefore minimize fuel consumption and maximize performance.
