Tests of dynamical scaling in three-dimensional spinodal decomposition

Dynamical density functional theory and its application to spinodal decomposition.

We present an alternative derivation of the dynamical density functional theory for the one-body density profile of a classical fluid developed by Marconi and Tarazona [J. Chem. Phys. 110, 8032 (1999)]. Our derivation elucidates further some of the physical assumptions inherent in the theory and shows that it is not restricted to fluids composed of particles interacting solely via pair potentia...

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...

Hydrodynamic spinodal decomposition: Growth kinetics and scaling functions.

We examine the effects of hydrodynamics on the late stage kinetics in spinodal decomposition. From computer simulations of a lattice Boltzmann scheme we observe, for critical quenches, that single phase domains grow asymptotically like t, with α ≈ .66 in two dimensions and α ≈ 1.0 in three dimensions, both in excellent agreement with theoretical predictions.
