blade speed
velocity of blade

The flow equations are solved using finite difference technique . using body - fitted curvilinear coordinate system treated the boundary conditions . by iteratively solving the flow governing equation and the blade equation , the design of axial flow pump impeller in the quasi - three - dimensional rotational flow can be performed according to the angular momentum distribution , the blade which was designed in the lifting method , flow channel and the blade thickness given
其次在流动无粘性、不可压及考虑叶片厚度的条件下，依据叶轮内的流动特性，推导了叶轮内三维流动周向平均流动控制方程以及叶片方程；在贴体坐标系中，采用有限差分法求解流动方程和叶片方程；在采用升力法设计出的叶片作为初始叶片、给定叶片速度矩分布、叶片厚度分布和叶轮轴面流道几何形状条件下，迭代求解流动控制方程及叶片方程，实现了轴流泵叶轮的准三维方法设计。
