Anomalous propagation of acoustic traveling waves in thermoviscous fluids under the Rubin Rosenau Gottlieb theory of dispersive media

Abstract

We report on an apparent anomaly associated with the compressible, thermoviscous version of what has come to be known as RRG theory. The difficulty in question, which does not appear to impact the lossless special case of this theory, manifests itself under the traveling wave assumption and has the shock-front of the resulting kink waveform and the (instigating) piston propagating in opposite directions. © 2013.
