Large-Eddy Simulation of Flow around Magnus Wind Turbine with Spiral Fins
An aerodynamic performance of Magnus wind turbines with spiral fins depends considerably on the direction of the cylinder rotation. In this study, to clarify a mechanism of how the difference between two directions of rotation occur, numerical simulations was conducted. In these simulations, overset grid method was used to simulate rotations of turbine and cylinders, and two kind of cylinders, with spiral fins and without spiral fins, were used in order to determine whether a flow phenomenon obtained as a result of the simulations is caused by spiral fins or by multi rotations of turbine and cylinders.
