TURBULENT FLOW SIMULATION THROUGH CENTRIFUGAL PUMP IMPELLER AT DESIGN AND OFF-DESIGN CONDITIONS

摘要

In the present paper, the 2D turbulent flow in a centrifugal pump impeller is simulated by using a k-ε turbulence model and the SIMPLEC algorithm improved by Chen, Y. S.. Predictions gave the velocity vectors, the pressure field and the turbulent kinetic energy profile in the pump impeller at design and off-design operating conditions.
