摘　　要：应用计算流体动力学技术选用K-ε模型,对轿车的外流场进行了数值模拟,分析了轿车周围的压力、流场分布。By applying computational fluid dynamics technology and adopting model, the 3-dimensional external airflow around a car body is numerically simulated. The results are analyzed and discussed. The results of pressure and velocity distributing is analyzed and discussed.
