Abstract

Wind Energy has become one of the important energy sources for many countries as it safe guards the environment from pollutionMicro wind turbines are wind turbines that produce less than 1000 watts of power and are mostly utilised for residential purposes in urban areas. The National Institute of Wind Energy(NIWE)had stated that in India, wind speeds rangesbetween 0 to 5 m/sin the urban areas. The wind-turbine blades are the critical component that converts the energy available in the wind. Micro-turbine blades should be developed to suit the wind conditions present in a given location. To boost power conversion, particular features like as vortex generators, bumps, and slats have been introduced to the blades in recent years.A delayed stall and a higher lift coefficient were the results of the adjustments. The "S1223" blade, which had a narrow airfoil and a high lift coefficient, was investigated in this article. It was originally designed for low-reynolds-number carrier aircraft. The blades were modified with bumps on the leading edge, similar to those of a humpback whale, to increase aerodynamic performance characteristics. The numerical calculations were performed on a 2-D blade spline and a 3-D rotor, with the results compared between the blades with standard and curved airfoil sections.Micro-turbines with modified blades should produce 75% more energy than rotors with standard blades.
