STUDY ON FLOWS THROUGH CENTRIFUGAL PUMP IMPELLER BY TURBULENT SIMULATION

摘要

A finite volume numerical method is presented for simulating internal tur-bulent flows on the blade-to-blade surface through a centrifugal pump impeller, in which, a mesh in body-fitted coordinates is generated for the computation. In detail, the SIM-PLEC algorithm is utilized for solving governing equations of incompressible viscous/turbulent flows through the pump impeller. The K-ε turbulence model is adopted to describe the turbulent flow process. Some worthwhile simulated results are presented.
