Abstract:Centrifugal pump is indispensable mechanical equipment in national economic sectors.The flow in the internal flow field is very complex.Thus it is necessary to use an efficient numerical simulation method to study them to guide practical application and provide reliable basis for the pump to improve and design.Using the commercial CFD software Fluent to simulate the machine of the flow field of IS140-125-400 type spiral centrifugal pump,in the frame of moving reference coordinate,using the finite volume method to disperse the Renault time-averaged Navier-Stokes equations.Selecting standards of k-ε turbulence model and SIMPLEC algorithm to solve and obtained the velocity and pressure distribution of the centrifugal pump respectively in different flow condition,which could real react the internal flow of the pump.Through the analysis and comparison,the conclusion was drawn that when it was running under near the standard conditions,the pump flow was the most stable.
Keywords:centrifugal pump  numerical simulation  velocity  pressure
