Dynamics of Phase Separation under Shear: A Soluble Model
N. P. Rapapa, A. J. Bray
Abstract
The dynamics of phase separation for a binary fluid subjected to a uniform shear are solved exactly for a model in which the order parameter is generalized to an n-component vector and the large-n limit taken. Characteristic length scales in directions parallel and perpendicular to the flow increase as (t5/ t)1/4 and (t/ t)1/4 respectively. The structure factor in the shear-flow plane exhibits two parallel ridges as observed in experiment.
