Basic Reseach Activities

Wave processes in multiphase media.

• evolution, amplification, and extinction of shock waves, effects of interphase exchange, bubble screens for extinction and amplification of shock waves, interaction of waves with targets, vapor explosion, obtaining of high pressures in a closed volume of bubble liquid by non-periodic small-amplitude actions.

Porous and crack-porous media saturated by liquid or gas:

• linear and non-linear waves, longitudinal and transverse waves with plane, cylindrical, and spherical symmetry, surface Rayleigh waves, transition of waves from one-phase to two-phase media, interaction with targets, effect of shock waves in the air on a target covered by a porous layer.

Pressure profiles in a stepwise wave in polymer and glycerin with air bubbles

Pressure variation in the liquid phase in a plane wave propagating in a saturated porous medium
