| 摘 要： | 在曲线坐标下将高分辨率AUSMPW激波捕捉格式扩展到三维问题。为了提高计算精度，采用三阶MUSCL格式，将AUSMPW格式与隐械时间推进法LU－SGS方法结合，应用于可压缩无粘和有粘流动的数散模拟，计算结果与文献中计算结果和实验数据相符，并将该格式与CD、TVD、FVS和FD格式进行了比较。 |

| Abstract: | It aims to extend high-resolution AUSMPW shock-capturing schemeto the multidimensional hyperbolic conservation laws in curvilinear coordinates. The third-order MUSCL shceme with Van Leer limiter is used to extend the basic first-order AUAMPW scheme to third-order spatial accuracy for all test cases. The equations are discretized by using a finite volume method. The present scheme combined with the LU-SGS scheme is applied to compressible inviscid and viscous flows. The computed results are compared with the experimental data or the other numerical results available in literature and good agreements between them are obtained. The AUSMPW scheme is also compared with CD, TVD, FVS and FDS schemes. |
