Spinodal Decomposition in Fluids

Effect of Convection and Viscoelasticity on Spinodal Decomposition in Fluids

V. KUMARAN Department of Chemical Engineering, Indian Institute of Science, Bangalore, 560 012, India. in viscoelastic fluids could be very different from that in simple fluids. In addition to the early, transition and late. stage growth, there is an intermediate stage where the scaling laws are different from those predicted by current theories of spinodal decomposition. Viscoelastic effects h...

Spinodal decomposition in microemulsions

Parallel Spinodal Decomposition

Spinodal decomposition encompasses the ordering dynamics of thermodynamically unstable phases. An example of spinodal decomposition is the separation of the metals in a binary alloy. Because physicists have been unable to develop a fully coherent, consistent , and calculable theory on spinodal decomposition, computational studies have served as valuable sources of information. However, since th...

Quantum spinodal decomposition.

We study the process of spinodal decomposition in a scalar quantum field theory that is quenched from an equilibrium disordered initial state at Ti > Tf to a final state at Tf ≈ 0. The process of formation and growth of correlated domains is studied in a Hartree approximation. We find an approximate scaling law for the size of the domains ξD(t) ≈ √ tξ0 at long times for weakly coupled theories,...

Spinodal Decomposition in Binary Gases

We carried out three-dimensional simulations, with about 1.4 × 10 particles, of phase segregation in a low density binary fluid mixture, described mesoscopically by energy and momentum conserving Boltzmann-Vlasov equations. Using a combination of Direct Simulation Monte Carlo(DSMC) for the short range collisions and a version of Particle-In-Cell(PIC) evolution for the smooth long range interact...
