Abstract

The frequency dependencies of velocity and attenuation of waves propagating along the fluid-filled cylindrical cavity in a saturated porous medium are investigated. The study is made in the framework of two velocity, two stress model of the porous medium, taking into account the non-stationary forces of interphase interaction. On the boundary between the fluid and the porous medium two types of boundary conditions, i.e. open and closed pores, are considered. It is found that the most significant impact on the velocity and attenuation of the primary acoustic mode in a cylindrical waveguide in a porous medium has a permeability of the porous medium
