Spherical Explosion

The spherical explosion propagation process in aqueous foam with the initial water volume content α10=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.

This paper discusses experimentally the advance and distribution of preformed,wet aqueous foam ow when it is injected into a horizontal rectangularcell with dierent transversal opening channels. Speeds of the simultaneousfoam fronts in each channel were obtained experimentally. Therelationship between bubble size and the opening of the channel, the apparentviscosity and the friction factor were obtained with experimental data.Experiments were performed under three dierent injection pressures. Thediversion of the foam ow into the transversal channel was also studied. Withthese experiments we show that the foam ow stream is aected by suddenchanges in the geometry.
