Abstract: The study of the incidence angle effect around a Savonius wind rotor on the numerical results was obtained using "SolidWorks Flow Simulation" softaware. The objective of this study is to observe the effect of the incidence angle on the aerodynamic structure characteristics. These results are presented in different transverse and longitudinal planes of the considered control volume. To validate the numerical results, we have developed an experimental approach to measure the flow velocity in
different positions of the test vein of our wind tunnel.
