Nonlinear acceleration waves in porous media

Mathematics and Computers in Simulation (MATCOM), 2009, vol. 80, issue 4, 763-769

Abstract: We review three theories explaining why waves in a diffusion problem can travel with a finite speed. We then briefly look at a class of equivalent fluid theories for sound propagation in porous media. Finally, we derive a Cattaneo model for an elastic material containing a distribution of voids. Nonlinear acceleration wave motion in such a class of materials is also considered.
