Abstract

<p> Color&hyphen;coded and vector&hyphen;arrow grid representations of the Poynting vector field are used to show the energy flow in and around a fluid&hyphen;loaded elastic cylindrical shell for both forward&hyphen; and backward&hyphen;propagating waves. The present work uses a method adapted from a simpler technique due to Kaduchak and Marston [G. Kaduchak and P. L. Marston, &lsquo;&lsquo;Traveling&hyphen;wave decomposition of surface displacements associated with scattering by a cylindrical shell: Numerical evaluation displaying guided forward and backward wave properties,&rsquo;&rsquo; J. Acoust. Soc. Am. <strong> 98 </strong> , 3501&ndash;3507 (1995)] to isolate unidirectional energy flows.</p>
