Abstract

The power generated in wind turbine depends on wind speed and parameters of blade geometry like aerofoil shape, blade radius, chord length, pitch angle, solidity etc. Aerofoil selection is the crucial factor in establishing the efficient wind turbine. More than one aerofoils in a blade can increase the efficiency further. Previous studies of different aerofoils have shown that efficiency of small scale wind turbine increases when NREL S822 aerofoil is used for wind speed on and above 10 m/s. This paper introduces a study on effect of low wind speed (V = 5m/s) on performance of blade profile. Aerofoils NREL S822/S823 are used for micro wind turbine with S823 near root and S822 near tip. Blade of 3m radius with spherical tubercles over entire span is analysed considering 50 angle of attack. The CFD simulation was carried out using ANSYS FLUENT to study the behavior of blade profile at various contours. The study shows that blade experinces maximum turbulance and minimum pressure near trailing edge of the tip of blade. The region also experinces maximum velocity of the flow. These factors results in pushing the aerofoil in upword direction for starting the wind turbine to rotate at the speed as low as 5m/s.
