将一维AUSM+ 格式扩展到三维任意曲线坐标 .为了获得高阶精度 ,采用了三阶MUSCL格式 .将AUSM+ 格式与LU SGS格式结合 ,对凸包通道跨音速无粘流动、平面叶栅跨音速和超音速无粘流动 ,以及喷管超音速粘性流动进行了数值模拟 .计算结果与文献计算结果和试验数据相符很好 .
Dimensional AUSM + format to three-dimensional arbitrary curvilinear coordinates.In order to obtain high-order accuracy, the third order MUSCL format is adopted.The combination of AUSM + format and LU SGS format has the advantages of non-viscous flow across hull channels, Supersonic non-viscous flow and nozzle supersonic viscous flow were numerically simulated.The calculated results are in good agreement with the literature calculation and experimental data.
