CFD research on car body

Abstract

In the design of the car body we need take consideration of cost and comfort for the customer now a car body manufacturing is very difficult due to the compotators the customer will the efficiency of the car as well as the shape design of the car the efficiency car is depends on the internal combustion engine as well as the aero dynamic design of the body the aero dynamic design of the car is the most critical aspect in car design In this paper we introduced the aero dynamic flow analysis of the 3d car model to evaluate the aerodynamic design parameter. we design the car model by using the catiav5r20 and we did cfd analysis on car body by using the Ansys 14.5 we calculate the velocity and pressure on car body.
