COUPLED POROSITY-FLUID CONCENTRATION FLUX-TEMPERATURE WAVES IN ISOTROPIC POROUS MEDIA

In this article, we study a problem on propagation of coupled porosity, fluid concentration flux, and temperature waves. We use a model formulated in previous papers for porous media saturated by a fluid flow, in the framework of non-equilibrium thermodynamics. We derive three modes of propagation in the one-dimensional and perfect isotropic case, and then we test the validity of the model. The waves propagation velocities are represented in diagrams as functions of the wave number. The derived results have applications in technological sectors such as seismology, medical sciences, geology and nanotechnology.

This article studies the propagation of coupled porosity, fluid concentration flux, and temperature waves using a model formulated in previous papers for porous media saturated by fluid flow in the framework of non-equilibrium thermodynamics. Three modes of propagation in the one-dimensional and perfect isotropic case are derived and the validity of the model is tested. The results, represented as wave propagation velocities in diagrams as functions of wave number, have applications in technological sectors such as seismology, medical sciences, geology, and nanotechnology.
