Investigation of axisymmetric wave flows under interaction of a spherical impact pulse with a barrier of aqueous foam

The problem of spherical explosion in the gas region with a protective foam layer is solved in a two-dimensional axisymmetric formulation using a two-phase model of a gas-liquid mixture that includes the laws of conservation of mass, momentum and energy of the mixture and the equation for the dynamics of the volume content of phases. The numerical implementation of the model was carried out by modifying the standard solver of the compressibleMultiphaseInterFoam of the open package OpenFOAM. The results of computer modeling are visualized using the ParaView graphical platform.
