SPINODAL DECOMPOSITION IN A HELE-SHAW CELL

As an experimentally realizable two-dimensional fluid system, we perform a cell-dynamical system simulation of a binary incompressible fluid that undergoes spinodal decomposition after a critical quench in a Hele-Shaw cell. Fluidity enhances fluctuations of interfaces, resulting in a form factor that continuously depends on the fluidity of the system. In this system, finite size coupled with the effect of incompressible flow is found to have a severe accelerating effect on the growth law.
