Abstract

A simple recursion is presented that finds exact solutions to the problem of two coupled axially-vibrating liquid-filled pipes.Fluid-structure interaction at pipe ends and junction, and along the pipe because of axial-radial Poisson contraction, is taken into account. The solutions obtained for a waterhammer problem show unprecedented details that resemble noise. Keywords waterhammer, pipe vibration, fluid-structure interaction, travelling wave, method of characteristics
