离心泵叶轮内宾汉流体湍流流场的数值计算

考虑宾汉流体本构关系特点，建立了任意曲线坐标系（ζ，η）下宾汉流体湍流流动的基本方程，应用压力加权校正算法，实现了速度场和压力场的关联，采用交错网格技术，解决了非物理压力振荡问题，在此基础上，对离心泵叶轮内回转面上宾汉流体湍流流动进行了数值模拟，并分析探讨了离心泵叶轮内宾汉流体湍流流动机理。

Numerical Study of Turbulent Flow on Bingham Fluid in Pump Imperller

Control equations of Bingham fluid are presented according to the Bingham fluid constitution equation. The pressure field and velocity field are correlated by a pressure correction equation. Using the staggered grid, the non physical pressure oscillation can be efficiently diminished. The numerical computations are performed for Binghem fluid in a pump impeller.
