摘　　要：完善了螺旋离心泵叶轮的曲面方程，使其与三维网格的自动生成和三维流场的数值模拟相适应；基于对泵内流动与油流试验结果的分析，提出和建立了非规则叶轮曲面方程。作为实例。In order to adapt automatic generation of 3 D grids and numerical simulation of flow field, the curved surface equations for the regular impeller of a screw centrifugal pump are improved and furthermore the curved surface equations for the irregular impellers are established based on the analyses of the flow field inside the pump and the results from an oilfilm experiment. Finally, the 3]D uneven grids for the regular impeller flow passage are automatically generated as an applicable example.
