Experimental Identification of the Longitudinal Wave Propagation Speed in Fluid-filled Elastic Hose
초록
In this paper, an experimental identification method is presented to identify the bulge wave and extensional wave propagation speeds in the fluid-filled elastic hose. An fluid-filled hose is hanged vertically for straight position. The exciting device of piston type is developed to generate the bulge wave and extensional wave in the elastic hose. Hydrophones are arranged in the fluid-filled hose linearly to measure the wave pressure. The wave speeds are estimated using the wavenumber-frequency spectrum analysis technique.
