Numerical Simulation on G4-73 Centrifugal Fan with Slotted Blades

Abstract:

Taking the G4-73№8D centrifugal fan as research object and utilizing the software of NUMECA to simulate flow fields of impellers with different splotted blades, the parameters of slotted blade are optimized through contrastive analysis of the effects on internal flow characteristics and performance. Results show that the optimized scheme can improve the uniformity of internal flow field, full pressure and efficiency seperatly increase by 4.25% and 1.49% under the design flow. For the needs of variable fan load operation, this paper puts forward the optimization principle of slit parameter.
