Intensification of Hydrate Formation during the Propagation of a Weak Pressure Wave in a Bubbly Liquid

This is the authors' abstract. We don't add key points for this paper.

This paper presents a numerical model describing the propagation of a step-type pressure wave of small amplitude in a bubbly medium containing the Freon-12 gas under hydrate formation conditions. The dynamics of waves in channels of constant and variable cross section is considered. The influence of surfactants on the tendency of bubble fragmentation is analyzed according to the Kelvin−Helmholtz instability mechanism.
