Abstract
Savonius rotors are a unique type of vertical axis wind turbine (VAWT) characterized by its S shape, with low rotational speed, low noise and good automatic start-up capability. This turbine has a great profile forsmall businesses and residences. The present work presents a simplified modeling of the fluid-structure interaction problem of a Savonius rotor, using the Fourier pseudospectral method (FPSM) coupled to the immersed bound-ary method (IBM), considering the Newtonian fluid, incompressible flow, without heat transfer and gravitational effects, with constant and two-dimensional (2D) properties. The results presented address the flow over a freely rotating vertical turbine, which allows the analysis of the evolution of the moment coefficient (Cm ) in relation to temporal evolution, azimuthal position (θ) and the blade tip speed ratio (λ).
