Abstract

Two-phase mixtures can evolve with time by the diffusion of mass from regions of high to low interfacial curvature, a process known as coarsening. Through the experiments on the International Space Station, we have employed a model two-phase mixture that both satisfies all the assumptions made by theory and in which all the materials parameters needed to compare theory and experiment are known. We find that the observed exponents and amplitudes of the temporal power laws for the average particle size and number of particles per volume, as well as the particle size distributions match those predicted by theory. We thus conclude that interfacial energy driven ripening is well described by existing theory. Extensions of this theory to systems in which the coarsening domains have spatially varying curvature, such as those found following spinodal decomposition or ordering, are discussed.
