Comparative analysis of two foam models

Calculated results are compared for several one-dimensional self-similar interactions of shock waves with a water foam. The results are calculated using 1) a cell model in which the foam is treated as a porous medium which is impenetrable to gas and 2) a single-velocity (equilibrium) model of a multicomponent medium. It is found that pulsations excited in foam bubbles by a shock wave must be considered.
