| Abstract: | This paper uses the "one-way Coupling" model and simplified "two-way coupling "model of gas-particle two phase flow for calculating erosion and deposition characterizations of centrifugal fan under four typical blade loading ways. The relationships between blade loading way and distribution rule of colliding angle, colliding velocity and erosion rate due to collision of particles with blade are discussed. The paper presents some new suggestion for design high efficiency fan with solid case. The effect of solid phase on fan's performence is experimented, and the prediction for erosion of fan with dilute gas-particle flow is proved. |
