Pressure on the interface between a converging fluid wedge and a fast fluid bottom

MetadataShow full item record
The pressure amplitude and phase distribution along the interface between a tapered fluid layer and an underlying fast fluid bottom were investigated both theoretically and experimentally. Two different theoretical models were compared experimentally: a simple model based on a combination of normal modes and ray theory and an exact solution based on the method of images. The experiment was conducted at 100 KHz with a wedge of silicon oil separated from a large tank of fresh water by a thin mylar diaphragm. The simple model failed to predict adequately the pressure amplitude and phase along the interface. The method of images gave accurate predictions.
