Abstract

This study aimed to investigate the effect of the overlap on the aerodynamic characteristics of the flow around a Savonius wind rotor. A numerical simulation was developed using a commercial CFD code. The considered numerical model is based on the resolution of the Navier–Stokes equations in conjunction with the k-ε turbulence model. These equations were solved by a finite volume discretization method. We were particularly interested in visualizing the velocity field, the mean velocity, the static pressure, the dynamic pressure, the turbulent kinetic energy, the dissipation rate of the turbulent kinetic energy, and the turbulent viscosity. The comparison of the numerical results with previous results shows a good agreement.
