AN EXPERIMENTAL ANALYSIS OF HORIZONTAL WIND TURBINE

Abstract

In the present global scenario, pollution has become the issue of prime concern. International community is holding meeting, after meeting to control the pollution and save the environment from pollution. The main factors which are responsible for the pollution are conventional method of power production by burning coal and other fossil fuels which emits an enormous amount of co2 gas and pollutes the environment. In the present work the power production by wind turbine has been emphasized and research has been carried out on design of rotor blade of wind turbine to have maximum mechanical power output and absolutely pollution free power produce. In this work the rotor blade of the wind turbine aerofoil section NACA 5510 has been roughened to have maximum drag at the lower face and to offer more and more lift on the rotor blade. Also to increase the blade area, a flap has been added at the end of blade trailing edge so that braking torque can be achieved at the lower wind speed. After taking the experiment in all cases it has concluded that power of the wind turbine has increased by 10% when rough surface blade are used and 21% when flap at trailing edge are used while compared to the wind turbine using smooth surface blade.
