Abstract
In this study, the influence of the shape on the characteristics of a Savonius
wind rotor was studied in numerical simulations and experimental measurements.
Particularly, we compared the features of the Savonius rotor with a new design rotor
consisting of a four-stage configuration. We used “Solid Works Flow Simulation” to
display the local characteristics in various transverse and longitudinal planes. The
Navier-Stokes equations and the standard k-ε turbulence model were solved in the
numerical model. A finite volume discretization method was applied to solve these
equations. The experimental measurements were conducted in an open wind tunnel to
validate the numerical model.
