The expected exhaustion of fossil sources of energy requires the improvement of other renewable sources, such as wind turbines. Vertical-axis wind turbines present very attractive performance characteristics but extremely complicated aerodynamics. Therefore, research is still needed on this field. A code is developed in order to apply the blade element momentum theory to these wind turbines. BEMT is shown to give considerably reliable results, compared to its fast convergence. BEMT is improved with dynamic stall and wake interaction modifications, in order to include more physical effects. Modified BEMT models will help obtain fast and qualitatively reliable data on VAWT performance. Comparisons with other authors prove that the generated code provides data that are close to the real results.
