Abstract

ABSTRACT In order to study the wetting characteristics of cylindrical droplets in a homogeneous and smooth annular two-layer capillary, based on the approaches of Gibbs's dividing surface and Rusanov's dividing line, a generalized Young equation describing contact angles has been successfully derived considering the effects of the line tension. Besides, under the hypothesis that the line tension is a constant, we also analyze this generalized Young equation to be reduced to the well known Young equation.
