Three-dimensional phase-field modeling of spinodal decomposition in constrained films

Computer simulation of spinodal decomposition in constrained films

The morphological evolution during spinodal decomposition of a binary alloy thin film elastically constrained by a substrate is studied. Elastic solutions, derived for elastically anisotropic thin films subject to the mixed stress-free and constraint boundary conditions, are employed in a three-dimensional phase-field model. The Cahn–Hilliard diffusion equation for a thin film boundary conditio...

Phase-field modeling of the dynamics of multicomponent vesicles: Spinodal decomposition, coarsening, budding, and fission.

We develop a thermodynamically consistent phase-field model to simulate the dynamics of multicomponent vesicles. The model accounts for bending stiffness, spontaneous curvature, excess (surface) energy, and a line tension between the coexisting surface phases. Our approach is similar to that recently used by Wang and Du [J. Math. Biol. 56, 347 (2008)] with a key difference. Here, we concentrate...

Spinodal Decomposition and the Deconfining Phase Transition

Lattice gauge theory investigations of the deconfining phase transitions have mainly been limited to equilibrium studies (an exception is the work by Miller and Ogilvie [1]). The equilibrium transition with two massless quarks is likely second order and it becomes a crossover with two light quarks (and the heavier strange quark) [2]. In nature the finite temperature phase transition is governed...

Molecular Dynamics Simulation of Spinodal Decomposition in Three-Dimensional Binary Fluids.

Three-dimensional lattice-Boltzmann simulations of critical spinodal decomposition in binary immiscible fluids.

We use a modified Shan-Chen, noiseless lattice-BGK model for binary immiscible, incompressible, athermal fluids in three dimensions to simulate the coarsening of domains following a deep quench below the spinodal point from a symmetric and homogeneous mixture into a two-phase configuration. The model is derivable from a continuous-time Boltzmann-BGK equation in the presence of an intercomponent...
