Rapid mass transfer caused by capillary phase separation and itsmodeling

考察了二元Lennard-Jones液相纳米界面平衡条件、纳米孔内二元Lennard-Jones液体的毛细管相分离以及纳米孔内毛细管相分离引起的传质现象。T^*或ε(AB)值越大，托尔曼长度越大，界面张力越小，平衡体积浓度越大。此外，在纳米孔中，阐明了体积浓度与传质速率之间的关系。拉普拉斯效应越强，半月面的曲率半径越小，孔内冷凝液体的内压越低。因此，放大压差应发生在两种不同体积条件之间的凝聚相中。

Nanoscopic interfacial equilibrium condition of binary Lennard-Jones liquid phases, capillary phase separation of binary Lennard-Jones liquids in nanopores, and mass transfer phenomenon caused by capillary phase separation in nanopores are examined. The larger the value of T^* or ε(AB), the larger is Tolman's length, the smaller is the interfacial tension, and the larger is the equilibrium bulk concentration. Moreover, in nanopores, the relation between the bulk concentration and rate of mass transfer was clarified. Curvature radius of the meniscus is smaller, the inner pressure of condensed liquid in pore is lower by stronger Laplace effect. Therefore, amplified pressure difference should be occurred in condensed phase nestled between the two different bulk conditions.
