Simulation and Analysis of the Outlet Flow Regime of the Centrifugal Pump Based on CFD Technology
摘要
Abstract
Taken the centrifugal pump which is widely used and has a low speed ratio as the study objection,and accord-ing to the working flow characteristics of the centrifugal pump,the mathematical model between the internal fluid and the centrifugal pump components is given on the basis of the theoretical principle of the current fluid mechanics development. Simulation analysis is carried out on the working condition of the centrifugal pump;the 3D solid modeling of the centrifu-gal pump is established and connected with the corresponding CFD technology, then through the key flow components of centrifugal pump meshing and optimization,and selecting the appropriate turbulence model,the outlet flow pattern of the pump body is numerically simulated which is closer to the reality. It is beneficial to observe the flow field, pressure and other parameters of the inlet and outlet of the pump,and summarize the related work characteristics,the research would be provide some reference value for us to further understand the mechanism of the internal fluid,improve the centrifugal pump structure, impeller performance and the parameter optimization, then achieve the goal of improving the hydraulic efficiency of the pump, which is a worth popularizing analysis method.关键词
