Abstract

A system of differential equations describing process of propagation of acoustic waves in a saturated saturated gas to a porous medium. A dispersion relation taking into account Interphase interaction forces and heat exchange processes between the skeleton porous medium, liquid and gas. Influence of heat exchange processes between phases on the nature of the propagation of ”fast“ and ”slow“ waves is taken into account on the basis of the heat conduction equations.

Keywords

a porous medium,
a ”fast“ wave,
a ”slow“ wave,
heat transfer,
a wave damping decrement,
a phase velocity of the wave
