Web1 de jun. de 2024 · Cahn–Hilliard–Brinkman system has been widely used to describe the phase separation and coarsening of binary fluids in Brinkman porous media [3], which is … 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
