On the cahn-hilliard-brinkman system
WebThe model couples a Cahn–Hilliard–Brinkman (CHB) system with a elliptic reaction-diffusion equation for a nutrient. The fluid velocity, governed by the Brinkman law, is not solenodial, as its divergence is a function of the nutrient and the phase field variable, i.e., solution-dependent, and frictionless boundary conditions are prescribed

Web28 de nov. de 2014 · A two-grid method for solving the Cahn-Hilliard equation is proposed in this paper. This two-grid method consists of two steps. First, solve the Cahn-Hilliard equation with an implicit mixed finite element method on a coarse grid. Second, solve two Poisson equations using multigrid methods on a fine grid. Webas the Cahn-Hilliard-Brinkman (CHB) system. In particular, the Brinkman equation is a Stokes-like equation with a forcing term (Korteweg force) which is proportional to µ∇ϕ, where µ is the chemical potential. When the viscos-ity vanishes, then the system becomes the Cahn-Hilliard-Hele-Shaw (CHHS) system.
