A Comparative Study On Hydrokinetic Turbine Of Blade Profile

Abstract

The objective of this project to design a prototype of river turbine that can convert hydrokinetic energy to electric and to compare the outcome from 3 different types of blade profile. This turbine is design for river application which river flow stream to drive the turbine. It operate a shallow river with the depth range from 1 meter to 1.5 meter. The turbine must be submerge to able operate smoothly. By using this results, the highest reading of which type of blade profile by producing electricity are the most suitable to solve the problems. Blade with radius 105° shows the reading of the voltage while the first and second design show difficulties in functioning to rotate smoothly and reading the data. This studies shows the blade with radius 105° show potential and can be apply to the turbine to generate electricity. Factor such as stream velocity, water flow, blade and frame design and depth of the river is the main factor that will affect the efficiency of the blade in generate electricity. River turbine has a great future as an alternative way in generating electricity especially in off-grid electricity location
