| 中文摘要 | 给出了离心泵叶片压力表面固液两相流体边界层控制方程和叶片压力面边界层分离参考点位置估算的一种方法,通过实例计算分析了相关的边界层参数,计算结果说明固液两相流的边界层厚度δ2随叶片弯曲系数Kν的减低和随质量浓度ρm的增加而减薄,并给出了对比试验的验证结果,结果是大于临界速度系数的叶片将使测试泵的性能有不同程度的下降,并且测试浓度的增加有抑制边界层分离的作用。它说明离心泵叶片压力面两相流边界层分离点的位置是随叶片形状的改变而移动的,是可以控制的。; The control equations of two phase flow boundary layer on vane pressure surface in centrifugal pump and a calculation method of the layer's reference separation point are given out. By practical example, relative boundary layer parameters are computed and analyzed. The result states that the thickness of the boundary layer δ2 will decrease as vane bending coefficient Kv decreases and mass concentration ρm increase. The certificated result of contrast test is given out, which the vane more than critical velocity coefficient will reduce the pump' properties in different degree, and increasing of test concentration can restrain the boundary layer separation. It is concluded that the separation point position of two phase flow boundary layer on vane pressure surface in centrifugal pump varies with changing of vane shape and so can be controlled. |
