Accelerated inertial regime in the spinodal decomposition of magnetic fluids

Abstract

Furukawa predicted that at late times, the domain growth in binary fluids scales as $\ell(t)\sim t^{2/3}$, and the growth is driven by fluid inertia. The {\it inertial growth regime} has...

Kinetics of phase separation and aging dynamics of segregating fluid mixtures in the presence of quenched disorder

“…Both diffusive growth (a = 1/3) and viscous hydrodynamic growth (a = 1) have been observed in numerous numerical simulations, while the inertial hydrodynamic regime (a = 2/3) has only been observed in lattice-Boltzmann simulations. 26,27 Studying the two-time correlation C cc (r,t,t w ), where t is the observation time and t w is the waiting time, is a useful tool for analyzing non-equilibrium dynamics. In equilibrium systems, the two-time correlation function exhibits time translation invariance, meaning that the results overlap due to the time displacement t À t w .…”
