Phase coexistence in consolidating porous media
Emilio N. M. Cirillo, N. Ianiro, Giulio Sciarra · Physical Review E · 2010
The appearance of the fluid-rich phase in saturated porous media under the effect of an external pressure is investigated. For this purpose we introduce a two field second gradient model allowing the complete description of the phenomenon. We study the coexistence profile between poor and rich fluid phases and we show that for a suitable choice of the parameters nonmonotonic interfaces show up at coexistence.
