液-汽相变的相场模型

A phase field model for liquid-vapour phase transitions

V. Berti, M. Fabrizio, D. Grandi

摘要:

我们提出了一个描述液-汽相变的相场模型。该模型采用了第二作者提出的设置,其中引入了相场,其平衡值0和1与液相和气相相关联。相场服从Ginzburg-Landau方程,进入密度本构关系,解释了在相变时发生的密度突变。在本文中,我们关注的是这个模型的扩展,考虑到共存线的临界点的存在。

英文摘要:

We propose a model describing the liquid-vapour phase transition according to a phase-field approach. The model takes up a setting proposed by the second author, where a phase field is introduced whose equilibrium values 0 and 1 are associated to the liquid and vapour phases. The phase field obeys Ginzburg-Landau equation and enters the constitutive relation of the density, accounting for the sudden density jump occurring at the phase transition. In this paper we concern ourselves with the extension of this model to take into account the existence of the critical point in the coexistence line.
