Abstract

In this paper, we studied geometric effects of impeller blade angles and hub configurations on the energy conversion efficiency of regenerative blowers, using commercial CAD and CFD software. As a base geometry, a regenerative compressor, that was commercially available with accessible experimental data, was modeled and simulated. Both Pro/Engineering (PTC) and SolidWorks (Solidworks Corp.) were used for 3D geometrical modeling, and ANSYS-CFX (ANSYS, Inc.) was used for CFD flow simulation. The CFD flow simulation was performed at a constant impeller rotational speed of 3600 rpm, while the air flow rates varied from 60, 80, 100, to 120 cfm. The simulation results for the base geometry agree with the experimental data, confirming the validity of the modeling and simulation schemes. For the parametric study of the impeller blade angles and hub configurations for enhanced efficiency, the two geometrical design parameters were systematically investigated to find out optimal efficiency points. The result shows that the protrusion and shape of a hub are more impactful to the pump efficiency than the outflow angles of blades, and enhances the power efficiency more effectively.
