Wetting and drying at a solid–fluid interface

Abstract
We have studied the wetting and drying transitions in a solid–fluid interace with truncated Lennard-Jones interactions, for which there have been reported molecular dynamics results by Sikkenk et al. [Phys. Rev. Lett. 59, 98 (1987)]. We consider in detail the differences resulting from the use of a ‘‘real’’ solid substrate instead of the ‘‘inert wall’’ model which has been used in all previous calculations.
