Ostwald Ripening in Two Dimensions: Treatment with Pairwise Interactions

Abstract

We present a systematic extension of mean field models for Ostwald ripening in two dimensions. We derived, using a mean field type approximation, an analytic expression for pairwise interactions between the minority phase droplets. These interactions appear in dynamic equations for the droplets' radii and positions, which are solved numerically for systems of tens of thousands of droplets, yielding very good agreement with recent experiments.
