Study of the Computational Domain Effect on the Aerodynamic Structure Around a Savonius Wind Rotor

This study aims to investigate the effect of the computational domain on aerodynamic characteristics of the flow around a Savonius wind rotor. For thus, we have developed a numerical simulation using CFD code. The considered numerical model is based on the resolution of the Navier-Stokes equations in conjunction with the standard k-e turbulence model. These equations were solved by a finite volume discretization method. Particularly, we are interested to visualize the velocity field, the mean velocity and the static pressure. The good comparison of our numerical results with anterior results confirms the validity of the numerical method.
