Design of High-Speed Magnetic Centrifugal Blower Impeller and Numerical Simulation of Internal Flow Field

Abstract:

Currently, most domestic blower speed is still in 3000r/min level. The friction loss of mechanical bearings results in their low efficiency. To further improve the efficiency of the fan, a new high-speed maglev centrifugal fan was developed specially. The design of impeller styles, structure and size are rational. 3D graphics of the impeller and volute were drawn by using solidworks software. Application of CFD flow analysis software and the SIMPLE algorithm described viscous flow field within the three-dimensional centrifugal fan. By comparing simulation data with calculated data, optimize the turbine design. The simulative results are basically consistent with the design data, which provides a theoretical basis for the design of a new high-speed magnetic levitation fans, improving the level of centrifugal fan design.
