| 摘 要： | 根据颗粒在流场中的受力公式．推导出了低Ｒｅ下颗粒在水轮机导水机构至转轮进口绝对运动的运动轨迹通解方程及高Ｒｅ下轨迹计算方程。在采用相对坐标的基础上，推导出了颗粒在水轮机转轮内的运动轨迹方程。最后，计算了不同颗粒在水轮机转轮内的运动轨迹含砂水中的转轮抗磨蚀设计提供了理论依据，具有重要意义。

| Abstract: | Based on the formulation of the force acted on the particle, this paper prestnts the general solution for a particle moving in the still and rotational coordinate system in the case of low Re, and the equation of trajectory for particle in the high Re is aslo obtained in the still and rotational coordinate system respectively. In the end, the trajectory on difforent condition of various particle diameter is calculated too. Iiis benefits the design of the antifriction and anticorrosion . |
