Numerical Simulation for Centrifugal Blower with MRF Model and Solution-Adaptive Feature

摘要

In order to understand the flow phenomenon in the whole field of centrifugal blower, the two-dimensional turbulent flow in blower is investigated by numerical flow analysis. The SIMPLE algorithm with multiple reference frame (MRF) model is used for the solution of the discretized equations based on the Navier-Stokes equations and the standard k- epsilon model. During the course, the solution-adaptive mesh refinement feature based on pressure gradient is adopted to refine the mesh in special part.
