Abstract
In this paper, using the Gibbs dividing surface method, the formula that determines the curvature-dependentsurface tension in a system with two phases is deduced. The well-known Tolman formula is a special case for this formula.The problem of a sessile droplet is considered. The Bashforth–Adams equation analogue in view of the curvaturedependent surface tension is obtained and the numerical solution of the equation is carried out. We show that if thedroplet size is not so large compared to the thickness of the surface layer (micro- or nanodroplets), the dependence ofthe surface tension on the curvature is very important.
