Effect of Drag on the Performance for an Efficient Wind Turbine Blade Design

Abstract The utilization of wind energy for power generation purposes is becoming increasingly attractive and gaining a great share in the electrical power production market worldwide. In the present study, a mathematical model is developed to study the parameters that affect the electrical power generated by the wind turbines. The considered parameters are turbine swept area, air density, wind speed, lift/drag ratio and power coefficient as a function of blade tip speed. The study shows that the operational aerodynamic parameters has a direct effect on the generated power which will lead the developers and researchers to focus on the highest aerodynamics priority that should be considered for manufacturing and suitable the new generations of wind turbines.
