A Two-Wave Empirical Model of the Pressure Field in a Liquid-Filled Cylindrical Shell.

Abstract

This report develops an empirical wave propagation model of the pressure field in a liquid filled cylindrical shell. Based on the assumption that both an extensional and a breathing wave are propagating in both the positive and negative axial directions of the shell, the model contains six unknown parameters: two forced wavenumbers and tour wave propagation coefficients. The forced wavenumbers are solved for initially and then two different inverse methods are used to determine the wave propagation coefficients. The empirical model is compared to measured data taken at various locations in the shell. A method to determine the accuracy of the model and model assumptions is discussed.
