摘要：

In this paper, numerical simulation and experimental validation were carried out to study the turbulent flow around a small incurved Savonius wind rotor. The software "Solid Works Flow Simulation" has been used to present the local characteristics in different transverse and longitudinal planes. The numerical model considered is based on the resolution of the Navier-Stokes equations in conjunction with the standard k-epsilon turbulence model. These equations were solved by a finite volume discretization method. Experimental results are conducted on an open wind tunnel equipped by a small incurved Savonius wind rotor to validate the numerical method. Use of this knowledge will assist the design of packaged installations of incurved Savonius wind rotor. (C) 2014 Elsevier Ltd. All rights reserved.
