Unsteady aerodynamic forces and wakes of rectangular prisms with oscillating flaps at leading edges
Abstract The main objective of this work is to demonstrate how the oscillation of separation points affects unsteady flows and aerodynamic forces of a rectangular prism in a uniform flow. Two flaps were attached at the leading edges to control steady separation angles and to give periodic disturbances on the springing shear layers. The steady and unsteady lifts were measured wit different steady angles and during oscillation of these flaps. Before the description of these results is given, the characteristics of aerodynamic forces such as drag, lift and moment acting on the rectangular prisms having various depth/height ratios() are presented from preliminary tests.
