含时Ginzburg-Landau模型中湿层凝结的动力学

Dynamics of condensation of wetting layer in time-dependent Ginzburg-Landau model

Masao Iwamatsu

摘要:

研究了润湿膜通过界面限制生长时,在基底上或毛细管内的液体冷凝动力学。我们使用一个唯象的含时Ginzburg-Landau(TDGL)型模型与长程衬底势。使用一个序参量,这并不直接代表密度,我们可以推导出一个解析公式的界面生长速度是直接相关的衬底电位。使用这个解析表达式的润湿膜的生长符合幂律型的增长,这是由于存在一个长程色散力。

英文摘要:

The dynamics of liquid condensation on a substrate or within a capillary is studied when the wetting film grows via interface-limited growth. We use a phenomenological time-dependent Ginzburg-Landau (TDGL)-type model with long-range substrate potential. Using an order parameter, which does not directly represent the density, we can derive an analytic formula for the interfacial growth velocity that is directly related to the substrate potential. Using this analytic expression the growth of wetting film is shown to conform to a power-law-type growth, which is due to the presence of a long-range dispersion force.
