Visualization of the energy flow for guided forward and backward waves in and around a fluid-loaded elastic cylindrical shell via the Poynting vector field
Journal of the Acoustical Society of America
Color‐coded and vector‐arrow grid representations of the Poynting vector field are used to show the energy flow in and around a fluid‐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 [G. Kaduchak and P. L. Marston, ‘‘Traveling‐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. 98, 3501–3507 (1995)] to isolate unidirectional energy flows.
