Abstract

In this paper, a numerical study is carried out to investigate transient flow of hydraulic installation during the starting period of a centrifugal pump. The pump impeller angular velocity variation is determined by simulating the dynamic law of the pump electric motor. Transient flow equations are solved by using the method of characteristic of specified time intervals. The computed head and discharge, caused by the starting time of the pump, are presented at some cross sections of the pipe. The results have shown that the evolution of the hydraulic variables is well influenced by impeller geometry and the motor torque starting time.
