叶轮机械中的三元固液两相流动理论研究

Study on the 3-D and Two-phase of Solid-Liquid Mixed Flow in the Runner of Hydraulic Machinery

本文根据所推导的固液两相基本方程，得到了水涡轮机械中固液两相流动的封闭方程。在此基础之上，基于两类相对流面，研究出了水涡轮机械三元固液两相流动的通用理论，对水涡轮机械中两相流动的流场计算及含砂水中的水涡轮机械叶片的抗磨蚀设计，都有十分重要的意义。

asing on the basic equaiton of two-phase of solid-liquid mixed flow,this atricle gives out the closed equation for two-phase of solid-liquid in the hydraulic machinery.Tehen,the general theory for 3-D and two-phase of solid-liqnid mixed flow is discussed according to the S1 and S2 finally, the 3-D and two-phase now fieldare calculated.
