Wave Motion in a Thick-Walled Fluid-Filled Hose
Abstract
The subject of this report is the analytical solution for wave motions, in the fundamental mode, of an elastic tube filled with fluid when the wall thickness is not constrained to be small. The results obtained show the existence of two waves which travel at different speeds. Each of the two waves causes both longitudinal and radial displacements of both the tube wall and the fluid, but in different proportions. The slower wave, in the limiting case of the thin-walled tube, is identified as the bulge wave. It is characterized by relatively large motions of the fluid, which contains most of the kinetic energy. Thicker walls produce a higher bulge-wave speed, but the inclusion of longitudinal stiffening elements has very little effect. The faster wave is what has been called the wall wave. This is mostly a longitudinal vibration of the hose material, with a relatively small participation by the fluid, and is greatly influenced by longitudinal reinforcement of the tube wall.
