| 摘 要： | 采用Beam-Warming/TVD格式，Roe二阶、三阶以及四阶通量差分分裂格式数值计算雷诺平均Navier-Stokes方程，湍流附加粘性采用Baldwin-Lomax模型计算，针对超声速绕钝圆舵流动进行了数值模拟比较研究，计算给出了流场的详细结构，物面压力分布与实验值符合良好，尤其是Roe三阶格式给出了较好的计算结果，两个超声速回流区以及湍流边界层分离也得到了很好的数值模拟。

| Abstract: | The Reynolds averaged Navier Stokes equations are solved numerically by Beam Warming/TVD scheme, Roe second order, Roe third order and Roe fourth order flux difference splitting schemes Baldwin Lomax model is adopted for turbulence flow Thus a numerical study with different high resolution schemes for supersonic flow over a blunt fin mounted on a flat plate is made The computed results display flow structure in detail The pressure distributions on the surface show good agreement with the experimental data Especially, the Roe third order scheme gives the best results among those schemes The existence of two reversed flow supersonic zones is observed in the results |
