EXPERIMENTAL STUDY AND NUMERICAL SIMULATION OF INTERIOR FLOW IN CENTRIFUGAL PUMP
In order to study the phenomena of two-phase flow with salt-out in centrifugal pump, it is important to investigate the real flow in the pump with clear water. Based on the Reynolds-averaged N-S equations and standard k-ε two-equation turbulent model, the 3D turbulent flow was simulated through the full flow passage by the fluid dynamics software FLUENT.PIV was also applied to measure the flow inside the modified centrifugal pump. Relative velocity distributions in the impeller were obtained. Combined with the results from numerical simulation and experiment,preliminary analysis of inner flow field in the centrifugal pump was presented. The experiment results also show that standard k-ε turbulent model used in simulation coincides with the inner flow of the pump basically.
