Computational and Experimental Study of a Coaxial Pipe Flow Generator

This study presents the research and develop of a Coaxial Pipe Flow Generator. Modern engineering tools such as Computational Fluid Dynamics (CFD) software and Rapid Prototyping (RP) technology were utilized to facilitate the numerical and experimental studies. The CFD numerical simulations consisted of three-dimensional steady state analyses. The simulations were performed to optimize blade shapes within the geometrical range. Based on the results from CAD simulations, different types of impellers were fabricated to test different turbine parameters. Rotational speed of the turbine and electrical voltages were measured for each turbine design. The study leads to several important findings for better pipe flow generator design.
