WebThe Cahn-Hilliard Equation Markus Wilczek 2015-07-21 The Cahn-Hilliard equation describes the process of spinodal decomposition of a binary mixture. We consider a binary mixture of the two components Aand B, which are described by their local per-volume densities c A(x;t) and c B(x;t), respectively. For a binary mixture, we can assume that c A ... Web对流 Cahn-Hilliard 方程为高阶且非线性程度强的反映扩散方程, 精确解难以求出, 故发展其数值解意义重大.本文讨论该方程的高精度有限差分方法.给出线性化紧差分格式.建立格式 …
