The London-van der Waals dispersion force concept is used to analyze the interline region of a falling evaporating thin film. Viscous flow significantly affects the upstream profile, e.g. the apparent contact angle. The slope of the liquid-vapor interface is equal to a dimensionless interline heat sink. An increase in the apparent contact angle causes an increase in the rewetting velocity. Large interline temperature gradients and superheats are possible with either a stationary or moving interline. The physical process whereby the interline of a falling evaporating film can be in contact with a superheated surface is described. © 1979.
