离心泵叶轮表面压力分布的面元法数值计算

Numerical Analysis for Impeller Pressure Distribution of the Centrifugal pump by Panal Element Method

本文把文献[1]面元法求解内部流场的思想,进一步推广到进行离心泵叶轮表面压力分布的研究,计算了不同叶轮形状、不同工况下的表面压力分布,并与相应的试验结果和其他方法的计算结果分别进行了比较,结果令人满意。

This paper extends for solving the flow field by a panal element method to study on the impeller pressure distribution of centrifugal pump. calculations are carried out for vans of arbitrary shape and different-working conditions. The calculated coefficients show good agreement with other prediction methods and model test result.
