耦合Cahn-Hilliard方程组的数值方法

Numerical Methods for a System of Coupled Cahn-Hilliard Equations

Mattia Martini, Giacomo Enrico Sodini

摘要:

在这项工作中,我们研究了一个系统的耦合Cahn-Hilliard方程描述的共聚物和均聚物共混物的相分离。我们提出的数值方法是基于对单个Cahn-Hilliard方程的现有方案的适当组合。作为验证我们的方法,我们提出了一些测试和详细描述的数值解的行为通过改变参数的值。

英文摘要:

In this work, we study a system of coupled Cahn-Hilliard equations describing the phase separation of a copolymer and a homopolymer blend. The numerical methods we propose are based on suitable combinations of existing schemes for the single Cahn-Hilliard equation. As a verification for our approach, we present some tests and a detailed description of the numerical solutions' behaviour obtained by varying the values of the parameters.
