Abstract: This paper presents a flow control method using micro-cylinder installed in front of the blade leading edge and invests the aerodynamic performance of the VAWT equipped with micro-cylinders. Numerical results suggest that the flow separation is effectively controlled by setting a micro-cylinder in front of the blade leading edge when the blade works at large attack angle. Meanwhile, the VAWT equipped with micro-cylinders has higher efficiency than regular VAWT under small tip speed ratio.
