Abstract

In this paper, computer simulation has been conducted to study the aerodynamic structure around an unconventional Savonius wind rotor with a 75° bucket arc angle. The numerical model is based on the resolution of the Navier-Stokes equations in conjunction with the standard k-ε turbulence model. These equations were solved by a finite volume discretization method. The software "Solidworks Flow simulation" has been used to characterise the flow characteristics in different transverse and longitudinal planes. The good comparison between numerical and experimental results confirms the validity of the numerical method.
