| 摘 要： | 本文用三维热流和三维边界层相互作用法求解叶轮中的粘性流动。在叶睡表面三维边界层计算中采用了半正交曲线坐标系，各向异性三维涡粘性的湍流模型，变换域技术和Keller分块解法。在叶轮流道及上下延伸体所组成的法语解域中的三维势流计算中，采用了直接边界元法。算例表明，本方法正确可行。

| Abstract: | The inviscid-viscous interaction is used to analyze the three dimensional viscous flow in impellers in the present paper. The semi-orthogonal curvilinear coordinates, the anisotropy eddy viscosity turbulence model and Keller box method are used for calculating three dimensional boundary layers on blade surfaces. The direct nonlinear boundary element method is applied to calculate the three dimensional potential flow in impeller passage. Calculated results are found in agreement with measure values. |
