摘要
应用ＣＦＤ方法进行车辆外部流场的数值模拟，可以获得任意截面与位置上的流速、压力等参数，不仅可以求得气动阻力系数等车辆空气动力学特性参数的大小，而且可以进一步分解各组成部分。介绍了近年所做的有关研究工作的进展并讨论了进一步的应用前景。在数值模拟中考虑了气体的可压缩性以提高计算精度，应用了所提出的组合网格划分方法，自行开发了大规模的三维流动数值模拟计算软件并通过计算实例进行验证，同时在实用化方面作了较大的努力。
With CFD method the flow field around the vehicle can be numerically simulated and the velocity and pressure in any position and section can be known. Not only can aerodynamic characteristics such as drag coefficient be but so can obtained their components. The progress of related research done by the author in recent years is presented and the application prospect is discussed. In order to raise accuracy, the gas compressibility in numerical simulation is considered and the combined mesh generating method proposed by the author is applied. The 3 D flow numerical simulation software is developed and with experimental data verified. At the same time great efforts for practicability of the software are made.
