An experimental study has been made on the jet-like flow induced by an elastically vibrating plate. In order to clarify the effects of configuration of the plate on the induced flow, time-averaged velocity decay along the center line of the jet has been measured by using a hot-wire anemometer. As a result, the flow filed was found to be categorized into three regions defined by characteristics of the axis velocity decays. By introducing a method similar to that applied to jets issuing from rectangular nozzles, measured velocity decays have been normalized. The normalized velocity decays obtained were found to he independent of both amplitude and frequency of vibration and showed geometrical similarity for the various plate configurations tested. Therefore the diagrams for normalized velocity decay are useful means to estimate the flow field induced by an elastically vibrating plate with various configurations.
