基于离散相模型的电潜泵叶轮磨损数值计算
Numerical calculation of particle erosion within electric submersible pump based on discrete phase model
摘要
Abstract
Based on discrete phase model and elastic-plastic indentation fracture theory, erosion in the electrical submersible pump impeller was numerically simulated. The effect of particle size and impeller speed on the erosion of the electrical sub-mersible pump impeller was predicted by a particle erosion model. In order to verify the results of numerical simulation, the erosion in an electrical submersible pump in operation was measured by the coordinate measuring machine. The results show that the critical diameter with the highest erosion rate is 0. 06-0. 08 mm. The erosion mainly occurs in the center of the con-cave surface of blade. With the increase of particle size and impeller speed, the erosion area will extend. The numerical sim-ulation results agree well with the testing results.关键词
