摘要
本文求解雷诺平均三维不可压Navier-Stokes方程,模拟轿车外流场,发展了方便快捷的前后处理技术,计算了东风AF微型轿车,计算结果与风洞试验结果很好地相符,开发的CFD软件可成为理解和优化轿车外流的有效工具。
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.
