Abstract
The Blade Element Momentum Theory (BEM), uses two methods to analyse the operation of wind turbines. The first method is the Blade Element Theory and the second one is the Theory of Quantity of Motion. In this theory the blade is divided in several elements. Each element of the blade has different velocities, chord and inclination angles, which makes each element to experience a slightly different flow. The combination of these methods generates equations that can be solve iteratively and, after being solved, provides an analysis of the wind turbines. In this study, the SCILAB was used to implement the Schmitz method to design the wind turbine and the BEM method to analyse. Numerical simulation was used though the software ANSYS, using the k- model, to verify the results obtained with Blade Element Momentum for a small wind turbine. It was possible to realize that the errors between the analytical method and the numerical simulation were small, and conclude that the forms of analysis are similar when their results are compared.
