二维离心流场叶片边界层方程

xx00Boundary Layer Equations of Vanes in Two-dimensional Centrifugal Flow Field

建立了简化成二维定常不可压缩流体的离心泵叶片的边界层方程,并对相关量进行了分析。强调构造边界层内速度分布函数并设法得到边界层厚度的迭代式式对求解边界层动量积分方程的重要性。

The boundary layer equations of vanes of centrifugal pump in two-dimensional incompressible fluid are set up and the relevant quantities are analyzed in the paper. At the same time, the speed distribution function )(hf is constructed, the iteration equation of boundary layer thickness )(xd is required and the momentumintegral equations of boundary layer are solved.
