Diffusional growth of wetting droplets
Abstract
Description
The diffusional growth of wetting droplets on the boundary wall of a semi-infinite system is considered in different regions of a first-order wetting phase diagram. In a quasistationary approximation of the concentration field, a general growth equation is established on the basis of a generalized Gibbs-Thomson relation which includes the van der Waals interaction between the droplet and the wall. Asymptotic scaling solutions of these equations are found in the partial-, complete- and pre-wetting regimes.
