The numerical modeling of spherical explosion in the foam

The spherical explosion propagation process in aqueous foam with the initial water volume content 10 = 0.0083 corresponding to the experimental conditions is analyzed numerically. The solution method is based on the one- dimensional two-temperature spherically symmetric model for two-phase gas-liquid mixture. The numerical simulation is built by the shock capturing method and movable Lagrangian grids. The amplitude and the width of the initial pressure pulse are found from the amount of experimental explosive energy. The numerical modeling results are compared to the real experiment. It’s shown, that the foam compression in the shock wave leads to the significant decrease in velocity and in amplitude of the shock wave.
