摘要
采用二维雷诺平均N-S方程和Spalart-Allmaras湍流模型对三种压缩面形状的旋转冲压压缩转子二维进气流道流场进行了数值仿真.计算结果表明,压缩面形状对二维进气流道中的波系结构和形状具有决定性影响,凸曲线压缩面二维进气流道的总体性能最佳.
The two dimensional Reynolds-averaged Navier-Stokes equations and the Spalart-Allmaras turbulent model are adopted to simulate the flow fields of the two dimensional flow-paths with three kinds of compression ramp shape in a ram-rotor.It has been found that the compression ramp shape has decisive influence on the form and structure of the shock waves in the two dimensional flow-paths. The overall performance of the flow-path with convex curve compression ramp is optimal.
