| 摘 要： | 本文以自吸式离心泵中的气液两相流为研究对象，利用湍流、射流理论中的Tolleimn平面平行射流边界层方程及气液两相流理论，在一定的假设条件下，得出变密度和无因次纵向速度方程，并拟合出了叶轮出口的排气量和自吸时间的计算公式。

| Abstract: | The two phase flow of gas liquid in the self priming centrifugal pump was regarded as study objective in the article. By using the boundary layer equation of Tolleimn plane parallel jet in the theory about turbulent jet and the two phase flow theory of gas liquid, the intensity and dimensionless longitudinal velocity of mixing flow were explained. The formulae of self priming time and air pumping rate were put forward under several supposed conditions. |
