Abstract
In this work, a vertical axis wind turbine Savonius type is computationally simulated on its static state at different positions, rotating the rotor at six different angles, from 0 to 150 degrees. The objective is to find the aerodynamic forces coefficients applied to the rotor, torque, lift and drag coefficients, and determine a range of the optimal positions which it could start operating without the use of external devices. The numerical simulation and all geometry generation are done by free and open source software. The code used is OpenFOAM; it is based on Finite Volume Method and computes the pressure and velocity fields of the flow to calculate the forces acting on the rotor buckets. The results are validated comparing with other published articles.
