Iteration Solution for a Submerged Force-Driven Finite Cylinder.

Abstract

A theoretical model has been developed to protect acoustic radiation from a submerged, finite-cylindrical shell internally stiffened by ring frames and with flat, movable end caps. Iterative techniques are developed to solve the associated fluid-structure coupled systems over a moderate range of frequencies which encompasses several fluid-loaded resonances. We demonstrate that such techniques generate essentially the exact solution in a reasonably small number of iterations. Comparison of computational costs to those for the exact result shows iteration to be economically advantageous for all frequencies considered. Keywords include: Fluid Structure Interaction, Iteration, Finite-length Cylindrical Shells, and Force-Driven.
