| Recent developments in wind energy technology have led to the emergence of the Magnus Vertical Axis Wind Turbine (VAWT), a novel configuration that leverages the Magnus effect to achieve efficient power generation under strong and unsteady wind conditions. This turbine features rotating cylinders combined with flat plates to produce unidirectional torque. Despite successful prototype implementations, there remains a lack of detailed numerical investigations addressing the aerodynamic performance of this design, particularly the complex flow interaction between the rotating cylinder and the flat plate. To address this gap, the present study focuses on optimizing the blade configuration of a Magnus VAWT and assessing the performance of multi-bladed Magnus VAWT rotors in turbulent flow conditions.
