为提高计算收敛速度 ,以新的高收敛率的 L U型隐式格式和高精度、高分辨率的 MUSCL TVD迎风格式为基础 ,对可压缩无粘和粘性流动问题计算的多重网格方法进行了探讨。采用二维凸包通道和 VKI LS 5 9跨音速透平叶栅为算例 ,通过与单网格上的计算迭代性能做对比 ,证明这种算法在原有基础上更大幅度地提高了计算收敛速度 ,节省了CPU时间 ,而且方法本身也简单易行 In order to improve the convergence rate of the computations, a new multi-grid method for compressible viscous and viscous flow problems was proposed based on the new LU-type implicit scheme with high convergence rate and the high-resolution, high-resolution MUSCL TVD windward scheme Discussion. By using two-dimensional convex hull channel and VKI LS 5 9 transonic turbine cascade as an example, it is proved that the proposed algorithm can greatly improve the convergence of the computation based on the original iteration compared with the computational iteration performance on a single grid Speed, save CPU time, but the method itself is also easy
