Abstract
The study of the propagation of disturbances in a bubble liquid is of considerable scientific and practical interest due to the wide spread of such systems in nature and in industry. In this study, wave processes are theoretically investigated in a two-speed porous medium saturated with water with gas bubbles on the pore walls. A dispersion relation describing the dependence of the complex wave vector on frequency is obtained, which is used to study the dependence of the phase velocity and the attenuation coefficient on frequency for «fast» and «slow» waves. It is established that for both types of waves there are three characteristic frequency ranges, where not only the quantitative but also the qualitative picture of the dispersion curves and the dependence of the phase velocity differ significantly. The influence of the characteristics of gas bubbles on the propagation of sound waves in a porous medium saturated with water with gas bubbles on the pore walls is studied.
