Acoustic wave propagation in two-phase heterogeneous porous media
J. I. Osypik, N. I. Pushkina, Ya. M. Zhileikin
The propagation of an acoustic wave through two-phase porous media with spatial variation in porosity is studied. The evolutionary wave equation is derived, and the propagation of…
Nonlinear three-wave interaction in marine sediments
N. I. Pushkina
Nonlinear interaction of three acoustic waves in a sandy sediment is studied in the frequency range where there is a considerable wave velocity dispersion. The possibility of an ex…
Acoustic wave front reversal in a three-phase media
N. I. Pushkina
Acoustic wave front conjugation is studied in a sandy marine sediment that contains air bubbles in its fluid fraction. The considered phase conjugation is a four-wave nonlinear par…
Nonlinear acoustic wave generation in a three-phase seabed
A. B. Kukarkin, N. I. Pushkina, Ya. M. Zhileikin
Generation of an acoustic wave by two pump sound waves is studied in a three-phase marine sediment that consists of a solid frame and the pore water with air bubbles in it. To avoi…
Nonlinear excitation of second sound in quantum solutions He3-He4 due to light wave absorption
N. I. Pushkina
Nonlinear excitation of second sound in superfluid solutions He3-He4 by light waves due to their absorption is discussed. Nonlinear wave equations that model the interaction of sec…
