A model of a shock tube is prepared to study the behaviour of a shock wave in a layer of light elastic granular particles. Computational experiments are made using the OpenFOAM package. The prepared model allows carrying out simulations for pressure between 10 5 and 10 4 Pa and concentration of particles of 20%. Results are obtained on pressures in different time moments, depending on different densities of granular particles. An increase of the density of the granular particles is shown to decrease the blurring of the boundary between the media. It is also noted that a decrease in the density leads to double pressure peaks.
