WebJan 1, 2008 · This chapter focuses on the Cahn–Hilliard equation. In the context of the Cahn–Hilliard equation, the two components could refer, for example, to a system with two metallic components, or two polymer components, or say, two glassy components. Frequently in materials science literature, concentration is given in terms of mole fraction … WebIn this paper we consider the Cahn–Hilliard equation with dynamic boundary conditions of Cahn– Hilliard-type first derived in Goldstein et al. (2011), or – as we will also refer to it – the Cahn– Hilliard/Cahn–Hilliard coupling, that is the fourth-order equation, for a function u : W [0;T] !R, u˙ =D Du+W0 W(u) in W; (2.1a) u˙ =D G
