Early Analysis of Jumping Water Effect on Breastshot Waterwheel for Microhydro Power Plant

Abstract

Mostly, micro-hydro power plant installed in irrigation cannels which flat slope uses waterwheel. The flat slope mean low static head of the flow, thus impacts low rotation speed of the wheel and finally low power output generated. In order to encounter the problem, it is important to developed effective waterwheel for flat slope water channels. The aims of thus work are to design and fabricate a water wheel with jumping water unit and also early analysis of effect of jumping water angle on rotation speed and power output of waterwheel. The waterwheel is installed downstream the jumping water unit, Meanwhile, triangle shaped jumping water unit has variation angle of 10°, 20°, 30°, 40°, 50°. The result shows that the rotation speed and power output increase with increasing angle of jumping water. The maximum rotation speed and power output are 30.86 rpm and 38 Watt at the jumping water angle of 50°.
