Magnus Wind Turbine Effect Vertical Axis Using Rotating Cylinder Blades

The aerodynamic characteristics of a Magnus wind turbine (MWT) with cylinder blades are evaluated by using numerical simulation COMSOL. Yaw and lifting systems are used to identify the features of the MWT to maximizing power output at minimum tresses, torque and fatigue. MWT is characterized by low efficiency of power production. Therefore, it is important to seek effective components to improve the power performance of MWT. The blades design in Yaw and lifting system are critical parameters that affect MWT performance. In this study, five suggestions were discussed to choose the best configurations of MWT in order to promote MWT application. Performance characteristics, such as stresses, Torque, deflection and fatigue with suggested configurations are analyzed and compared to identify the desirable components for this type of MWT. The results showed that the aerodynamic characteristics of MWT in this study will be presented as a significance guide for the initial research and preliminary design of MWT. Based on the suggested design configuration, the results showed that the Von Mises stresses are low at the bottom and high at the top, and the buckling is very high at the top but low at the bottom of the base while the maximum value of Findley's fatigue is for the bottom as a result of axial stress. As for the designed shaft, the force increases when the stress increases accordingly, therefore, the deflection also increases. Moreover, the results showed more specified ranges of stresses distributions on blades and deflection ranges of decrease and increase that enable for better design, control and power utilization of turbine.
