Design, Fabrication and Performance Test of Axial Flow Hydro Turbine

Abstract

Hydropower is the source of renewable energy for more than a century leading to a decrease in the burning of fossil fuels which
has an effect on the environment. The axial flow hydro turbine is placed for a small water flow rate and the low head application. Axial flow hydro turbine consists of guide vane mounted in the stationary casing and blades connected on the hub. Axial flow
hydro turbine consists of four runner blades, the number of guide vane is 6 and the guide vane angle is 73˚. In this research, the
available head and flow rate are 3.4 m and 0.14 m3/sec. Hydrofoil shape of runner blade selected NACA 6412 and modeling the
blade geometry used SolidWorks software. In this research, the modal of the axial flow hydro turbine is made with thermoplastic
filament material due to produce easily. The turbine assembly was tested with various water velocities at Lon Town Irrigation
Channel in Madayar Township, Myanmar. Experimental results of turbine shaft power and generator output power are also
estimated in this research. The maximum turbine shaft power and generator output power are observed 3.66 kW and 3 kW at
volume flow rate of 0.15 m3/s.
