Abstract
The shock wave (SW) propagation in an aqueous foam layer is investigated for the conditions of new published experimental data with visualization of the dynamics of the foam's volume liquid fraction under SW impact. A mathematical model has been developed that describes the behavior of the foam as a non-Newtonian fluid taking into account the effective Herschel-Bulkley viscosity, interfacial heat transfer processes according to the Ranz-Marshall model and realistic equations of state that describe the thermodynamic properties of aqueous foam components. The model is numerically implemented in the solver created by the authors in the OpenFOAM package. The influence of the behavior of the aqueous foam on the SW evolution is analyzed.
