Abstract

New mathematical models of a sessile drop and a captive bubble are constructed taking into account the size dependence of surface tension. If the Tolman length tends to zero, the well-known Bashforth–Adams model can be considered a special case of the constructed models. The contact angles at various values of the equilibrium volume are numerically calculated. The size dependence of surface tension is shown to lead to a violation of the conditions of consistency between the contact angles of a drop and a bubble in an external force field.
