Aerodynamic Simulation of Flow around Automobiles |

| Abstract: | The Reynolds averaged incompressible Navier-Stokes equation of 3-D turbulent flow are solved by CFD technique to simulate the outer flow field around cars. An easy-to-use and efficient pre/post processing technique is developed. Aerodynamic characteristics of a real Dongfeng AF minicar are simulated. The results have a good agreement with wind tunnel testing. The CFD software developed will be a valuable tool in understanding and optimizing the flow around a car. |
