Cahn-Hilliard Equations and Phase Transition Dynamics for Binary Systems
摘要:
二元体系的相分离过程可用Cahn-Hilliard方程描述。本文的主要目的是利用经典的Cahn-Hilliard方程和与熵耦合的Cahn-Hilliard方程对二元体系的动态相变进行分类,并得到一些有趣的物理预言。分析是基于非线性系统的动态过渡理论和新的分类方案的动态过渡,最近开发的作者。
英文摘要:
The process of phase separation of binary systems is described by the Cahn-Hilliard equation. The main objective of this article is to give a classification on the dynamic phase transitions for binary systems using either the classical Cahn-Hilliard equation or the Cahn-Hilliard equation coupled with entropy, leading to some interesting physical predictions. The analysis is based on dynamic transition theory for nonlinear systems and new classification scheme for dynamic transitions, developed recently by the authors.
