In this study, a liquid flow in two-, three- and four-stage centrifugal pumps was numerical investigated. The continuity and Navier-Stokes equations with the k-ε turbulence model and standard wall functions were used by means of the ANSYS-CFX code. To enhance the design of the multistage pump, the impacts of the number of impeller blades, diffuser(More)
In this paper, a numerical characterization of a first stage of a high capacity multistage centrifugal pump was performed for very high flow rates. A particular emphasis was placed on the diffuser design procedure. For this purpose, the equations of the continuity and the Navier-Stokes accounting for the boundary conditions were used by mean of ANSYS-CFX(More)
