摘要
将车辆外部流场视为三维定常可压缩气体的紊流流动来进行数值模拟，求出了车辆外部三维的压力、流速分布情况，获得了车辆外形与气动阻力系数等车辆空气动力学特性的定量关系；探讨了数值模拟的数学模型与计算方法和提高计算精度与加速收敛的措施。
The flow field around
vehicles is numerically simulated as 3 D steady compressible turbulent flow. The 3 D distribution
of pressure, the velocity around vehicles, the quantitative relationship between the vehicles
shape and aerodynamic characteristics are obtained. Aimed at practical design, a combined mesh
generating method proposed by the author is applied, and the modeling, algorithm of numerical
simulation, and the means to raise the accuracy as well as to accelerate the convergence are
investigated. The calculation result is verified with the experimental data.
