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。 In view of the full three-dimensional potential flow field in a hydraulic machine runner, an effective calculation method is proposed in this paper. This method takes into account some practical features of the rotor flow field, such as uneven blade loading and vortex flow at the outlet of the blade. Due to the use of nonlinear boundary elements, the proposed method can be widely applied to deviate from the design conditions. The result of the example is in good agreement with the measured data.
