Abstract:
Two models of a multistage centrifugal pump using a five- and six-stage centrifugal pumps were developed
and numerically investigated. The continuity and Navier-Stokes equations with the k-ɛ turbulence model
and standard wall functions were used by means of the ANSYS-CFX code. To enhance the design of the
multistage pump, the concept consisting of varying three parameters at a time was used. Thus, the combined
effects of the impeller blade angle, the impeller blade number and the impeller blade width on the
performance of the five- and six-stage centrifugal pumps was analyzed. The results obtained reveal, among
other things, that the highest pump efficiency was reached for the outlet impeller blade angle of 25.38°, the
number of impeller blades of 7, and the impeller blade width of 7 mm.
