A Modeling Study Focused on Improving the Aerodynamic Performance of a Small Horizontal Axis Wind Turbine

The excessive burning of the fossil fuels has excessively changed global temperature in last few decades. warming caused due to initiated a need increasing use renewal energy sources. wind is one renewable sources that can mitigate dependency on fuels. For locations with low-to-medium speeds (less than 7 m/s), main problem starting turbine. To start stationary turbine, not only it necessary overcome inertia and static friction but angle incidence relative blade profile also needs be favorable. Thus, at low speeds, resulting torque enough It is, therefore, incorporate good design requirements turbines. In this paper, modeling study performed using Pro/E, ADAMS MATLAB software improve behavior horizontal axis turbine for Cherat location northern areas Pakistan. yearly average speed Pakistan less 5 m/s. element momentum (BEM) theory used calculate optimized parameters (blade angles chord lengths) correspond maximum torque. Based parameters, Pro/E models were developed imported As compared initial model, increased from 22.5 N-m 28 coefficient performance (COP) 0.42 0.49 tip–speed ratio 4. should exceed resistive torques bearing friction, generator static, dynamic rotor order was successfully improved, model showed an ranges.
