Abstract
We present a numerical study of the transmission of a shock-wave pulse from a gas into a porous medium saturated with a bubbly liquid. The process is modeled for one-dimensional planar motion under the assumption of a viscoelastic porous skeleton. We examine the dynamics of a shock pulse propagating within a porous medium saturated with a gas-liquid mixture, considering the cases where the skeletal matrix consists of either sandstone or unconsolidated sand. The analysis focuses on the influence of both the shock pulse parameters and the properties of the gas-liquid mixture on the wave dynamics.
