Spinodal Decomposition of Binary Fluid Mixtures in Two Dimensional Systems

Surface-directed spinodal decomposition in binary fluid mixtures.

We consider the phase separation of binary fluids in contact with a surface, which is preferentially wetted by one of the components of the mixture. We review the results available for this problem and present numerical results obtained using a mesoscopic level simulation technique for the three-dimensional problem.

Spinodal decomposition of chemically reactive binary mixtures.

We simulate the influence of a reversible isomerization reaction on the phase segregation process occurring after spinodal decomposition of a deeply quenched regular binary mixture, restricting attention to systems wherein material transport occurs solely by diffusion. Our theoretical approach follows a diffuse-interface model of partially miscible binary mixtures wherein the coupling between r...

Cascades and spectra of a turbulent spinodal decomposition in two-dimensional symmetric binary liquid mixtures

We study the fundamental physics of cascades and spectra in two-dimensional (2D) Cahn-Hilliard-Navier-Stokes (CHNS) turbulence, and compare and contrast this system with 2D magnetohydrodynamic (MHD) turbulence. The important similarities include basic equations, ideal quadratic invariants, cascades, and the role of linear elastic waves. Surface tension induces elasticity, and the balance betwee...

Periodic spinodal decomposition in a binary fluid under shear

2014 Light scattering techniques have been used to study the phase separation of a sheared binary fluid of nitrobenzene and n-hexane at critical composition. Shear was seen to prevent the development of decomposition. The system is quenched when the shear is removed, allowing anisotropic spinodal decomposition rings to appear. When a periodic (frequency 03A9) shear was applied, a permanent anis...
