Calculating the thermodynamic properties of planar and spherical liquid-vapour interface

We present results of calculations of the equilibrium density profile and related surface properties for liquid-vapour interface of simple fluids. The interface has been considered to be (i) planar and (ii) spherical, with some attention paid to the stability of small liquid droplets. These calculations are based on density functional theory, in particular the gradient approximation, in conjunction with the simplified random phase approximation Bhatia-Young model for the bulk liquid.
