| 摘 要： | 从流体力学的基本理论出发，分析了固体颗粒在任意流场中的受力，导出了该流场中稀疏固体颗粒的运动方程，同时导出了固体颗粒在柱坐标系下的水涡轮机械流场中的运动控制微分方程式，给出了求解颗粒运动的数值计算方法，并求解了固体颗粒在一混流式水轮机转轮流场中的运动轨迹。

| Abstract: | An analysis is made of the forces acting on the solid particles in an arbitrary flow field.The Suffman force due to the velocity gradient and Magus force due to the particle rotationneglected in many earlier papers are considered in this paper. The equation for particle mo-tion in a flow field in hydraulic turbomachines is derived with Nowton's Second Law,A nu-merical method for solving the 3-D particle motion equation is given and the calculation re-sults for that in a Francis turbine runner have been obtained. |
