Abstract: This paper presents the performance evaluation results of a radial discharge centrifugal pump obtained through experimentation and CFD simulation. The paper also presents a brief theory behind the difference in the performance of a centrifugal pump operated in pump mode and turbine mode. The pump CFD simulation is performed with Star CCM+ simulation software. The pumps studied are both mono block radial discharge centrifugal pumps with rated speed of rotation per minute as 1400 and 2800 and specific speeds 20.65 (m,m3/s) and 35.89 (m,m3/s) respectively. The CFD results were first validated for pump mode by comparing them with the manufacturer provided performance curves. The results of CFD simulation for turbine mode operation are then compared with experimentally obtained results. The paper also presents a brief theory about PAT concept.
