Abstract
Energy generation has been a great point of preoccupation for centuries. Recently, as fossil fuels are seen as a finite resource, the researches for self-sufficient production of energy are increasing. Wind energy is a clean solution for this problem; however, a deepest study in the area needs to be done. In this context, this paper presents a qualitative analysis about blades’ profile of wind turbines. Its importance is justified due its role in the main element used for energy removal, the rotor, where the blades make direct contact with the wind, spinning to transfer fluid energy to mechanical energy, which will later be transformed into electricity. In this essay, two profiles were used for computer simulation, the NACA 63-415, a symmetric one, and NACA 6412, an asymmetric one. Graphs about the change in the velocity, temperature, pressure and turbulence of both types of blades were plotted and simulated with support of the software ANSYS. After the analysis, it was found that for zero degrees angle of attack, the asymmetric profile is the most indicated.
