| Abstract |
A mathematical model of granulated media
impregnated with a liquid and acted upon by an acoustic wave
is proposed. Theoretical fundamentals are developed and a laboratory
installation is created for measuring inertial and elastic properties
of such media on the basis of a resonance method. This installation
has been tested and utilized for measuring the "dynamic" density
and bulk elastic modulus of natural and artificial samples of
granulated media. A number of qualitative effects are established
and analyzed. We have identified and measured the dependence
of the dynamic density on the wave frequency. We have investigated
vibrations of the system depending on the shape of the samples
and their position in the resonator, as well as on the elastic
compliance of the resonator (Corteveg's correction). The results
of the complex theoretical and experimental investigations of hydrodynamic
characteristics of granulated media impregnated with a liquid that
have been carried out are of interest in both scientific and
applied aspects for hydroacoustics and marine geophysics. |
