In this review, we present control methods for flow over a bluff body such as a circular cylinder, a 2D bluff body with a blunt trailing edge, and a sphere. We introduce recent major achievements in bluff-body flow controls such as 3D forcing, active feedback control, control based on local and global instability, and control with a ...
WebA streamlined body has a smooth flow and a narrow wake. A bluff body generally produces large-scale flow separation, originating at the extremities or corners of the body, and a broad wake containing low pressures, thereby creating high overall drag. ...
