Bulk Viscidity Model in Acoustics of Bubbly Water Saturated Soil

The paper deals with a model for acoustic wave propagation in a bubbly liquid mixed with sand (water-saturated soil) based on the evolutionary equations. The cell-model is used for the Rayleigh equation derivation for a single bubble dynamics in a porous medium, and the governing equations for non-linear acoustic waves are derived. The obtained canonical equations can explain some experimental data of three-phase media acoustics.
