Abstract

The paper presents a numerical strategy for the simulation of phenomena disclosed by very recent experimentation within the framework of microscale studies devoted to the investigation of dissolution phenomena in liquid couples with a miscibility gap. Possible approaches to the problem are reviewed and discussed through a focused and critical comparison of similarities and differences, advantages and intrinsic limitations. The proposed technique comes through major modification of existing volume tracking methods. Some effort is devoted to demonstrate its relevance when trying to capture the fluid-dynamic instabilities dependent on mechanisms at the liquid/liquid interface driven by non-equilibrium thermodynamic conditions.
