Abstract

<p> The Poynting vector field is used to show the energy flow in the near&hyphen;surface region of an ensonified fluid&hyphen;loaded elastic cylindrical shell for both forward and backward propagating waves. The present work uses a method adapted from a simpler technique due to Kaduchak and Marston [Kaduchak & Marston, ‘‘Traveling&hyphen;wave decomposition of surface displacements associated with scattering by a cylindrical shell: Numerical evaluation displaying guided forward and backward wave properties,’’ J. Acoust. Soc. Am. <strong> 98 </strong> , 3501–3507 (1995)] to isolate unidirectional energy flows.</p>
