Anisotropic Spinodal Decomposition under Shear Flow

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...

Isogeometric analysis of the advective Cahn-Hilliard equation: Spinodal decomposition under shear flow

We present a numerical study of the spinodal decomposition of a binary fluid undergoing shear flow using the advective Cahn-Hilliard equation, a stiff, nonlinear, parabolic equation characterized by the presence of fourth-order spatial derivatives. Our numerical solution procedure is based on isogeometric analysis, an approximation technique for which basis functions of high-order continuity ar...

Adhesion under Shear Flow

The 4 integrin, 4 7, plays an important role in recruiting circulating lymphocytes to the gastrointestinal tract, where its ligand mucosal addressin cell adhesion molecule-1 (MAdCAM-1) is preferentially expressed on high endothelial venules (HEVs). Dual antagonists of 4 1 and 4 7, N-(2,6-dichlorobenzoyl)-(L)-4-(2 ,6 -bis-methoxyphenyl)phenylalanine (TR14035) and N-{N-[(3,5-dichlorobenzene)sulfo...

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...
