Computer simulations of domain growth and phase separation in two-dimensional binary immiscible fluids using dissipative particle dynamics.

摘要: We investigate the dynamical behavior of binary fluid systems in two dimensions using dissipative particle dynamics. find that following a symmetric quench domain size R(t) grows with time t according to distinct algebraic laws R(t)\ensuremath{\sim}${\mathit{t}}^{\mathit{n}}$: at early times n=1/2, while for later n=2/3. Following an asymmetric we observe only and if momentum conservation is violated see n=1/3 times. Bubble simulations confirm existence finite surface tension validity Laplace's law. Our results are compared similar which have been performed previously molecular dynamics, lattice-gas lattice-Boltzmann automata, Langevin conclude dynamics promising method simulating properties such systems. \textcopyright{} 1996 The American Physical Society.
