Nonlinear spontaneous oscillations at the liquid/liquid interface produced by surfactant dissolution in the bulk phase.

摘要: The results of theoretical and experimental studies spontaneous nonlinear oscillations produced at the liquid/liquid interface by surfactant transfer from a point source situated in one bulk phases are presented. analysis is based on direct numerical simulation system evolution. experiments performed for heptane/water using middle-chain aliphatic alcohols as surfactants. oil/water compared with corresponding data obtained air/water interface. presented allow conclusion that auto-oscillations air/liquid interfaces governed very similar mechanisms but their characteristics strongly dependent properties two contacting media, particular, partition coefficient.
