Paper Details

The centrifugal pump is the most used pump type in the world. The flow analysis inside thecentrifugal pump is highly complex mainly due to 3D flow structure involving turbulence, secondaryflow, cavitation and unsteadiness. In recent years, a growing availability of computational resourcesand progress in the accuracy of numerical methods brought turbo machinery Computational FluidDynamics (CFD) methods from pure research work into the competitive industrial markets. Thecritical review of CFD analysis of centrifugal pumps along with the future scopes for furtherimprovement is presented in this paper. CFD technique has been applied by the researchers to carryout different investigations on centrifugal pumps viz. performance prediction at design and off-designconditions, parametric study, cavitation analysis, diffuser pump analysis, performance of pumprunning in turbine mode etc. Unsteady Reynolds-averaged Navier–Stokes equations together with twoequation k-ε turbulence model were found to be appropriate for CFD analysis of centrifugal pump.Volute flow study and impeller-volute interaction appeared as an interesting research fields for thefurther improvement in the pump performance. The most active areas of research and development arethe analysis of two phase flow, pump handling non-Newtonian fluids and fluid–structure interaction.
