摘要
采用椭圆型方程生成空间网格，运用有限容积法和Eκ－ε。模型计算了三维湍流轿车外流场，相应的模型试验表明，两者结果基本一致。
The spacing grids are generated by elliptic system, and the Navier-Stockes equations of 3-D steady incompressible turbulent flow are solved by the finite-volume method and Ek-ε model to simulate the outer flow field around the sedan. The present numerical results are found to be in broad agreement with the wind tunnel testing.
