Computer simulation study of the local pressure in a spherical liquid-vapor interface

The pressure profiles across a liquid-vapor interface introduced previously [J. Chem. Phys, 106, 635 (1997)] have been evaluated with the aid of molec ular dynamics simulations for a system of particles interacting via a (trun cated and shifted) Lennard-Jones potential. This investigation extends earl ier results [J. Chem. Phys. 106, 635 (1997)] to spherical interfaces. Furth er evidence is found that, for the range of curvatures investigated, the su rface tension is curvature independent while the investigation of larger cu rvatures is prevented by the considerable noise found on the liquid side of the interface.
