摘要
针对水力机械转轮中全三维势流流场,本文提出了一种有效的计算方法。此法考虑了,如叶片不均匀负荷,叶片出口的旋涡流动等转轮流场的一些实际特征。由于采用了非线性边界元,文中所提出的方法可以广泛地适用于偏离设计的工况。算例结果与实测值吻合很好。
The present paper proposes a fully three-dimensional numerical method for potential flow through an impeller by using nonlinear boundary element method. Some practicalfeatures of the flow were considered, for example, nohuniform loading on blades and existence of vortex sheets at the trailing edges. Owing to the use nonlinear boundary element method, extensions to off design conditions can be easily obtained. The calculated results agree very well with the experimental data.
