“…The model of two compressible isothermal media with identical phase pressures and velocities was used in [5,6] to solve the problem of spreading of a compressed stratified medium. The studies described in those papers were focused on investigating the decay of a discontinuity formed by breakdown of a diaphragm between the high-pressure chamber containing the stratified layer of the substance (sand or Plexiglas) at the initial time and the low-pressure chamber filled by the gas.…”

Interaction of an incident shock wave with a layer of a porous material located near a solid wall is studied with the use of two mathematical models. The layer is modeled by a mixture of solid and gaseous phases. The mathematical models used are the equations of mechanics of equilibrium heterogeneous media with allowance for the gas pressure only and the model of two compressible media with identical partial pressures of the components. Verification of the approaches used is performed by comparisons of numerical results with experimental data.

“…This work is a continuation of research started in [3] and deals with interaction of a rarefaction wave with a layer of solid particles on a rigid boundary. The volume concentration of particles in the mixture is approximately half of the total volume of the layer.…”

Interaction of a rarefaction wave with a layer of solid particles near the end face of a shock tube is considered. A one-dimensional unsteady approximation of mechanics of heterogeneous media with identical pressures of the phases and with allowance for a finite volume concentration of particles in the layer is used as a mathematical model. The wave pattern of the flow and the mechanism of wave interaction with the layer, including the dynamics of the layer boundary depending on the layer thickness and rarefaction-wave width, are determined. The mathematical model proposed is verified against the dependence of the layer-boundary coordinate on time and also the dependence of the velocity of upward motion of the layer on the difference in pressures between the high-pressure and low-pressure chambers.
