The objective of this paper is to investigate the suppression of the fluid forces acting on a square prism by controlling the separated shear layer, Flow control is established by introducing a fine flat plate in on one side of the separated shear layer. Measurements are carried out with variations of the position, width and attack angle of the flat plate. Subsequently, the steady and unsteady fluid forces, vortex-shedding frequency and flow pattern are systematicallyexamined. Furthermore, such matters as the mechanism of flow control, the nature of the controlled wake, the relationship between the characteristics of the controlled fluid forces and behavior of the flow are discussed in detail on the basis of the obtained results of fluid forces and flow pattern.
