Abstract

Previous work [Cleon E. Dean and James P. Braselton, ‘‘Visualization of the energy flow for a guided forward wave in and around a fluid loaded elastic cylindrical shell,’’ J. Acoust. Soc. Am. 109, 2379 (2001)] showed the energy flow for a forward propagating fluid loaded elastic cylindrical shell at the resonance frequency. The results were difficult to interpret since although the two counterpropagating guided waves were separated and displayed independently, the conventional grid of vector arrows was hard to interpret in part because they were hard to see individually. The current work uses color encoding to show the Poynting vector field. Hue is used to indicate the direction of the energy flow while intensity of the color is used to denote the magnitude of the Poynting vector at that point.
