旋转喷射泵集流管内部流动计算

Turbulent flow calculation for collecting tube in roto-jet pump

对旋转喷射泵集流管内三维不可压缩湍流流动进行了数值模拟计算。计算采用连续方程、动量方程、k ε紊流模型、交错网格和Simplec算法。计算结果首次揭示了旋转喷射泵集流管内部的压力、速度以及湍流动能的分布规律。

The three-dimensional turbulent flow in the roto-jet pump's collecting tube is investigated by numerical simulation calculation. The simplec algorithm with staggering grid system are used in the solution procedure of the discretized equations based on the continuum equation and momentum equation and the standard k-ε model. The result shows the distribution of pressure, velocity and k in the collecting tube for the first time. The result can be used to predict the collecting tube's performance and optimization design of the collecting tube.
