Inertial effects in three-dimensional spinoidal decomposition of a symmetric binary fluid mixture: a lattice Boltzmann study. (English) Zbl 1049.76052
From the summary: The late-stage demixing following spinodal decomposition of a three-dimensional symmetric binary fluid mixture is studied numerically, using a thermodynamically consistent lattice Boltzmann method. We combine results from simulations with different numerical parameters to obtain an unprecedented range of length and time scales when expressed in reduced physical units. (These are the length and time units derived from fluid density, viscosity, and interfacial tension.) Using eight large $$(256^3)$$ runs, the resulting composite graph of reduced domain size $$l$$ against reduced time $$t$$ covers $$1\lesssim l\lesssim 10^5$$, $$10\lesssim t\lesssim 10^8$$. Our data are consistent with the dynamical scaling hypothesis that $$l(t)$$ is a universal scaling curve.
