This study explores hydroelastic buffeting of a flat plate experimentally. The flat plate is hinged vertically to an elastic axis, and its only degree of freedom, therefore, is rotation in pure yaw about this axis. Buffeting is a type of flow-induced oscillation which is caused by unsteadiness in the incoming flow. The laboratory technique presented here was applied for buffeting stimulation of the flat plate in water current. A bluff body was placed in the upstream of the flat plate to impose the unsteadiness. During the experiments, the distance between the bluff body and the flat plate was changed several times to assess the effect of distance on buffeting behavior. According to results, for distance ratios greater than 1, the buffeting responses are independent of distance ratio, although they are dependent on Reynolds number. Also the feasibility of hydrokinetic energy harvesting through buffeting is discussed.
