Abstract :
Centrifugal pumps are one of the turbomachines mostly used in different industries. The current research aims to determine the pump`s best working condition, where it must be run at minimum energy input with the optimum effectiveness, using a numerical technique such as computational fluid dynamics. The whole test (CFD) is performed using the commercial software ANSYS CFX 15.0. ANSYS CPD with a 22.5 ° angle of outlet blade and 6 sets of blades produced the pump`s geometry. The current assessment has shown that the pump`s effectiveness is reduced as the mass flow rate is increased. A second parameter, like the centrifugal pump slip factor, is calculated. The average slip factor calculation value is 0.83, the highest value for calculating the slip-factor in the Wisner analytical model.
