采用一种新型的LU隐式算法及4-5阶高分辨率TVD格式求解了叶轮机械内的三维N-S方程和q-湍流模型。应用几何法与PDF方法混合的网格生成程序,得到了ROTRO37跨音速压气机转子内的H型网格, 并将数值模拟的结果同LDV实验值进行了比较。
A new LU-type implicit scheme and an improvedfourth (fifth)-order high resolutionMUSCL TVD scheme were used to solve the full three-dimensionalNavier-Stokes equations and the q- low-Reynolds-numbertwo-equation turbulence model in turbomachinery.The three-dimensional viscous flow field in NASA ROTOR-37,which had been measured by LDV for detail,was evaluated by the present method with the aid of three-dimensionalgrid generation code based on geometry method combined with PDE solver.The computational results compare well with experimental data.
