PROPAGATION OF COUPLED POROSITY-TEMPERATURE WAVES IN ISOTROPIC POROUS MEDIA.

In this paper an application of a non-equilibrium thermodynamic theory developed in previous papers for porous media filled by a fluid flow is given. A problem of propagation of coupled porosity and temperature waves is explored in a special case. For perfect isotropic media and in the one dimensional case the dispersion relation is worked out and three modes of propagation are derived. The diagrammes of the waves propagation speeds as functions of the wave number are represented for given values of some phenomenological coefficients present in the elaborated model. The carried out results have applications in several fields of science, as seismic waves, biology, medical sciences, nanotechnology and geology. [ABSTRACT FROM AUTHOR]
