Effect of Variation of Design Parameters on Cross Flow Turbine Efficiency Using ANSYS

Abstract

Most of the major micro hydro power plants in Nepal uses Crossflow turbine for power generation which are manufactured locally. However, efficiency of these turbines has not been tested and verified. In this research, Cross flow turbine designs were obtained from local manufacturers. Efficiencies of these turbines were determined using simulation under steady state condition. Efficiencies were verified using the data from the installation site where these designs were used. Different Cross flow turbine models were prepared by varying the curvature radius of the blade and the ratio of inner to outer radius of the runner. The efficiencies of such models were determined using simulation.Journal of the Institute of Engineering, 2017, 13(1): 1-9
