旋喷泵叶轮内部流动的全三维数值模拟

Three-Dimensional Numerical Simulation of Internal Flow Within the Impeller Of Roto-Jet Pump

文章分析了旋喷泵叶轮流道的物理模型,建立了流道内部流动解析的数学模型,自行开发软件对旋喷泵叶轮流道内部流动进行了全三维势流分析,计算了叶轮产生的理论扬程,同时应用工具软件Fluent对叶轮内部流动进行了计算。通过对两种方法的计算结果进行比较,证明了该计算方法的可行性。

Based on the analysis of the physical model of the impeller of roto-jet pump, the analytical mathematics model of internal flow within the impeller is set up. By exploiting software, analysis of three-dimensional potential flow within the impeller of roto-jet pump is carried out, and the theoretical head obtained by impeller is calculated. At the same time, the commercial software Fluent was applied to calculate the internal flow. Compared with the results obtained by above two methods, the method is proved to be feasible.
