Study of Impeller Design for Pipe Flow Generator with CFD and RP

摘要

Design optimization is performed in this study for Pipe Flow Generator. Emphasize are on the impeller parameters including the geometry and the number of the blades. Modem engineering tools such as Computational-Fluid-Dynamics software and Rapid-Prototyping technology are utilized, to facilitate both numerical and experimental studies. In CFD numerical simulation, two dimensional transient analyses are conducted to investigate the relationship between the flow rate and the blade geometry, as well as the number of the blades. During experimentation, Rapid Prototyping technology is used to fabricate more than 30 different blades for comparison. RPM and corresponding Voltages are measured for different impeller designs. The study leads to several important findings and the results are very informative for better design of the pipe flow generator.
