【摘要】 提出了一种离心泵叶片反问题的新方法,该方法以轴面流线上的动量矩为控制变量,利用沿等m线上的速度梯度方程及连续方程来求解轴面相对速度,结合流线的微分方程通过控制轴面流线上动量矩的分布来控制叶片形状的。算例表明所提出的离心泵叶片反问题方法是可行的,同样能适用于其他类型的叶片泵,而且容易编制计算程序,实现泵叶片反问题的快速计算,充实了叶片泵的反问题研究。更多还原

【Abstract】 A sort of new inverse method of centrifugal pump blade is proposed, and in this method the distribution of momentum is considered as control variable. The continue equation and the relative velocity equation on isoline of streamline are used to calculate the relative velocity on meridian streamlines, and the blade geometries is determined by distribution of momentum and the differential equation of streamline. The calculation case shows that the new method proposed is practical, and still it can be used in other pump design conditions. The method is easy to calculate by program, and the inverse methods theory of centrifugal pump is further enriched.更多还原
