Contact Angles of Lennard-Jones Liquids and Droplets on Planar Surfaces

Publikation: Bidrag til tidsskriftTidsskriftartikelForskningpeer review

Abstrakt

The contact angles of liquids and droplets of Lennard-Jones particles on a solid surface are determined bymolecular dynamics simulations. The simulations show that the angles of contact are established within thefirst fluid layer. The droplets are not spherical segment-shaped. For an attractive surface corresponding to asmall contact angle, the observed contact angles disagree with the corresponding angles obtained formacroscopic systems and using Young’s equation and its extension for droplets with line tension.
