【摘要】 本文讨论了用三维有限元法来解水力机械转轮内部的流动问题。计算时假定绝对流动无旋。计算区域包括两个叶片之间的部分,并向上、下游各延伸一段。上游侧面可以不是流面,下游侧面必须为流面,因此其位置也是求解对象。应用这一方法计算了一个轴流式转轮,可以看出,结果是合理的。更多还原

【Abstract】 The internal flow in rotating hydro-machine runners has been calculated by finite element method. Assumptions are made that the flow is incompressible, and irrotational relative to fixed coordinate axes. The region of computation consists of the space between two blades and its upstream extension bounded by given lateral surfaces, and its downstream extension bounded by unknown stream surfaces to be determined as a part of the solution. Reasonable results have been obtained by applying the method to an axial flow runner.更多还原
