    Springer Science and Business Media LLC
    The process of reflection of acoustic waves through a porous medium in the case of their oblique incidence have been considered. It has been shown that as the angle of incidence increases, there is a decrease in the transmission coefficient.

  • Dynamics of acoustic waves in porous media saturated with gas-vapor mixture
    I. K. Gimaltdinov, V. L. Dmitriev, and L. F. Sitdikova
    Pleiades Publishing Ltd
    Wave processes in wet porous media saturated with gas-vapor mixture have been studied with allowance for interphase interaction forces and heat and mass exchange between the skeleton of the porous medium and the gas-vapor mixture. Dispersion relations have been obtained for a porous medium saturated with gas-vapor mixture, vapor, or gas.

  • Evolution of a wave pulse propagating through a porous obstacle
    I. G. Khusainov and V. L. Dmitriev
    Pleiades Publishing Ltd
    This paper studies the evolution of a wave pulse during propagation through a porous obstacle located in a gas and saturated with it. The cases of open and closed boundaries of the porous obstacle are considered. The effect of the parameters of the porous medium such as the initial value of the gas volume fraction and pore size and interfacial heat transfer on the evolution of the wave pulse was analyzed.

  • The propagation of linear waves in humid, gas-saturated media
    S. V. Volodin, V. L. Dmitriev, and I. G. Khusainov
    Pleiades Publishing Ltd
    The process of propagation of acoustic waves in humid, gas-saturated porous media is investigated in a two-velocity approximation. A dispersion relation is derived, which includes interphase interaction forces and heat transfer between the skeleton of porous medium, liquid, and gas. The effect of heat transfer between the phases on the propagation of the “fast” and “slow” waves is included by means of heat equation

  • Thermal shock under the action of radiation energy on a porous medium partially filled with gas hydrate

    Consideration has been given to the process of decomposition of a gas hydrate saturating a porous volume under the action of the energy of radiation through its boundary. It has been adopted that the zone lying in the vicinity of the boundary and saturated with the products of decomposition of the gas hydrate is transparent to radiation; the far zone saturated with gas hydrate and gas, conversely, is completely opaque; therefore, the radiation energy is totally absorbed at the boundary of phase transitions between the zones mentioned. The self‐similar solutions of plane one‐dimensional and radial‐symmetric problems have been constructed. The influence of the radiation intensity and of the parameters of the porous medium–solid gas hydrate–gas system in the initial state on the maximum pressures produced in the zone of decomposition of the gas hydrate has been analyzed based on the analytical solutions obtained.
