摘　　要：介绍了国内外在应用计算流体力学(CalculationFluidDynamics)对车身外流场数值模拟的研究发展状况。如今,国外CFD软件正朝全自动划分网格、高速高精度的计算方面发展,而国内对CFD的研究发展还处于一个初级水平。归纳了可用于汽车外流场数值模拟的方法及特点,最后指出了汽车外流场数值模拟目前面临的主要问题和发展趋势。The development situation of research on the flow field calculation simulation around automobile with the application of calculation fluid dynamics inside and outside is introduced. Now at abroad CFD is heading or generating mesh entirely automatically at a high speed and high precision, yet the development of CFD is still at primary level at home. The desirable methods and characteristics of the numerical simulation for automotive flow field are concluded. Finally, the main problems faced at present and development trends are pointed out.
