Performance Evaluation of Hydrokinetic Turbine by Varying Meridional Blade Region

The hydro-energy plays an important role in power sector with zero carbon emission. This paper introduces hydrokinetic pipe turbine. The hydrokinetic turbine is used which is installed in the circular cross-section pipe. The head of 2–3 m is used to give sufficient momentum to water which is used to rotate the horizontally placed hydrokinetic turbine to generate power in the range 50–60 kW. In this type of turbine, a shock free flow blade profile is developed on MIXFLO software. The software provides features of varying stagger angle to get good blade profile and validation with pressure coefficient plot for shock free flow. In the study, the meridional blade region is varied which is equivalent to varying orientation of the blade of the turbine. The 0.5 m blade region gives better efficiency, so the turbine performance is evaluated by considering this region.
