Abstract
A vortex generating apparatus includes: a member to contact with a flow of a fluid to form a stagnation point and a first and a second separation points on a periphery of a cross section of the member parallel to the flow; a disturbance applying unit to apply a disturbance to an upstream side of the first separation point to cause part of a boundary layer of the flow to adhere; and a controller to temporally control the application of the disturbance to change an adhesion distance from the stagnation point to the first separation point so as to generate a dynamic stall vortex.
