摘要
Abstract
Based on the standard k - e turbulence model, the three - dimensional flow in a whole multi - stage and multi -outlet centrifugal pump is numerically simulated using CFX software. By analyzing the pressure and flow field distribution in pump with different outlet settings, showing that the flow of the stage in the downstream of the pump outlet is zero, the flow field of the stage is in the self - loop state accompanied by large energy loss, and it produces a large pressure, resulting in a certain impact on the pump strength and reliability. Furthermore, the performance curve of the pump is determined based on the simulation results, it indicates that when the pump out is set in the last stage of pump, the head and efficiency reaches its maximum, and the position of pump outlet is more forward, the head and efficiency drops more. Finally, by comparison with the experimental performance curve, the accuracy of the method and results are verified. 关键词
