MODELING THE INTERACTION OF A SHOCK WAVE WITH A LAYER OF A GAS-PERMEABLE GRANULAR DEFORMABLE MEDIUM
A mathematical model is described and the main points are given for numerically implementing a two-rate model of a densely-packed granular porous medium with the gas-filled porous space. Using the implemented model, the processes of the passage of a finite length pulse through the "pure gas−porous medium" boundary and its reflection from the rigid wall behind the porous layer are investigated. The effect of the parameters of the model on the wave propagation and reflection processes is studied.
