Poroacoustic front propagation under the linearized Eringen–Cattaneo–Christov–Straughan model

Abstract

Employing the Laplace transform and its properties, we investigate the evolution of the coupled thermal and fluid-acoustic waveforms that arise in a signaling problem under the Eringen–Cattaneo–Christov–Straughan model of poroacoustic phenomena. Assuming a Heaviside temperature input, we determine the effects of what we term the “Eringen coefficient” by examining the propagation and evolution of the resulting shock and/or acceleration waveforms. Special/limiting cases are also discussed and, in the final section of this Note, possible follow-on studies are suggested.
