The utilization of wind energy has been well known for centuries, mainly for irrigation purposes. It is also known that wind energy can be converted to electrical energy using a wind-turbine generator especially in remote areas wind energy generation such as that produced by small-scale wind turbines installed in remote areas can be defined as micro-generation. There is a growing interest in the use of wind power in remote areas for distributed generation. Since the generated power is a function of the wind turbine blades and the wind speed, while a small increase in the wind speed leads to a large difference in wind power generation. For installation, an easy fabrication with low cost was the most important challenge. Therefore, it is in our interest to assess properly the wind turbine blades and suitability of these blades at remote areas and attempt to enhance them by using various proposed models investigated aerodynamics by Computational Fluid Dynamics (CFD). Half circle, carved airfoil and semi carved airfoil proposed models are tested. The first model offers a high force compared with others at the same wind velocity. This paper also highlights the potential to increase such systems’ economic attractiveness and their acceptance by the user with simple design.
