Spinodal decomposition in fluids: Diffusive, viscous, and inertial regimes

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

A velocity decomposition approach for moving interfaces in viscous fluids

We present a second-order accurate method for computing the coupled motion of a viscous fluid and an elastic material interface with zero thickness. The fluid flow is described by the Navier-Stokes equations, with a singular force due to the stretching of the moving interface. We decompose the velocity into a “Stokes” part and a “regular” part. The first part is determined by the Stokes equatio...

Double diffusive reaction-convection in viscous fluid layer

In the present study, the onset of double diffusive reaction-convection in a uid layer with viscous fluid, heated and salted from below subject to chemical equilibrium on the boundaries, has been investigated. Linear and nonlinear stability analysis have been performed. For linear analysis normal mode technique is used and for nonlinear analysis minimal representation of truncated Fourier serie...

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...
