Modelling, simulating and visualising the Cahn-Hilliard-Cook field equation

چکیده
The Cahn-Hilliard-Cook equation continues to be a useful model describing binary phase separation in systems such as alloys and other physical and chemical applications. We describe our investigation of this field equation and report on the various discretisation schemes we used to integrate the system in one-, twoand three-dimensions. We also discuss how the equation can be visualised effectively in these different dimensions and consider how these techniques can usefully be applied to other partial differential equations.

متن کاملThe existence of global attractor for a Cahn-Hilliard/Allen-Cahn equation
In this paper, we consider a Cahn-Hillard/Allen-Cahn equation. By using the semigroup and the classical existence theorem of global attractors, we give the existence of the global attractor in H^k(0
متن کاملNumerical Simulation and Role of Noise in the Cahn-Hilliard-Cook Equation below the Critical Dimension
Introducing stochastic or thermal noise into partial differential equations that would otherwise be deterministic is a useful technique for the analysis of ensemble simulations. It can also aid the unfreezing of structural growth barriers that occur in spatial growth systems. This article presents some modelling experiments using Cook’s noise term in the Cahn-Hilliard-Cook equation simulated on...
متن کاملFinite Element Approximation of the Linearized Cahn-hilliard-cook Equation
The linearized Cahn-Hilliard-Cook equation is discretized in the spatial variables by a standard finite element method. Strong convergence estimates are proved under suitable assumptions on the covariance operator of the Wiener process, which is driving the equation. The backward Euler time stepping is also studied. The analysis is set in a framework based on analytic semigroups. The main part ...
متن کاملThe Cahn-Hilliard-Cook Equation on Curved Surfaces in Three-Dimensional Space
Abstract Phase separation and coarsening is a phenomenon commonly seen in binary physical and chemical systems that occur in nature. One model which takes into account additive stochastic noise is the Cahn-Hilliard-Cook (CHC) model. Often, the surface on which phase segregation occurs is not a flat surface. With this motivation, we present a semi-implicit numerical algorithm to solve the fourth...
