Abstract

The paper is devoted to a theoretical investigation of wave processes in moist porous media saturated with gas. Interfacial forces of interaction, heat exchange between the skeleton of a porous medium, liquid and gas, mass transfer between a liquid and a gas; material of the skeleton of a porous medium is considered viscoelastic, the liquid covers the inner surface of the pores of the medium with a thin uniform layer. The propagation of acoustic waves is considered in the two-velocity approximation. A common system is recorded equations and physical relationships describing the propagation of acoustic waves in a wet porous medium. A dispersion relation is obtained. Influence of heat transfer between phases on propagation ”Fast“ and ”slow“ waves is taken into account on the basis of the heat conduction equation.
