摘要
本文基于 N - S方程和 K—ε紊流模型 ,对于所选择的五个工况点 ,采用贴体座标系和交错网格系统 ,用 SIMPL EC算法对水泵水轮机转轮内部的紊流进行数值模拟 ,得出了转轮内部流场和压力场的分布。将计算结果用 Tecplot7进行处理 。
In this paper, the simulation of the three\|dimensional turbulent flows through a hydraulic pump turbine runner at pump modes has been conducted based on κ\|ε turbulence model with body\|fitted coordination and staggering grid system. SIMPLEC algorithm is adopted in the numerical procedure. Velocity distributions and pressure distributions through the impeller are indicated. The results of three\|dimensional turbulent flows are displayed by a commercial software, Tecplot+3D Flow, version 7 0.
