Evolution of liquid systems with non-equilibrium component distribution

Abstract

The evolution of systems of liquids with a non-equilibrium distribution of components is experimentally studied, where the diffusion process leads to the emergence of bulk and surface flows, as well as to deformation of the interfacial surface. In particular, the stability has been studied for a horizontal interfacial boundary during surfactant diffusion in a two-layer system of immiscible liquids of similar density. The evolution of the shape of droplets is traced, which are in the conditions of neutral buoyancy in a density-stratified solution. Data on the contraction of the most common aqueous solutions of alcohols, acids, bases and their salts have been obtained and analyzed.
