Abstract—

A two-phase model of aqueous foam is proposed. It is based on the laws of conservation of mass, momentum, and energy of the phases in accordance with the single-pressure, two-velocity, and two-temperature approximations in the axisymmetric formulation, with account of the interphase drag forces, contact heat transfer, viscoelastic properties, and foam syneresis. The thermodynamic properties of the water and the air are described by the Mie—Grüneisen and Peng—Robinson equations of state, respectively. The model is numerically realized in the OpenFOAM software. The results obtained are in reasonable agreement with the experimental data on the spherical explosion in aqueous foam. The evolution of a spherical shock wave propagating in the aqueous foam is analyzed.
