As wind power generation systems have been common in these days, it is required to improve the efficiency of wind turbine blades, leading to its operational stability and high efficiency. It is introduced in this paper control methods for flow separations with simple devices, by which some improvements of airfoil characteristics can be achieved. By discussing experimentally the effects of both vortex generator installed on the upper side of blade surface and cylindrical rod set in the upstream of the blade on the airfoil characteristic, there methods are effective for improvements of the airfoil performance due to suppressed stall. The aerodynamic characteristics of the device is also verified by measuring the flow velocity just after the blade and by flow visualization using tuft grid method.
