Multiscale approach to model steady meniscus evaporation in a wetting fluid

Abstract

Evaporation flux in the thin transition film close to the wall is up to 100 times greater than at the center of a wetting meniscus. Despite higher evaporation flux, the thin film accounts for a relatively small part of the total evaporation from the liquid-vapor interface. The thin-film contribution is directly proportional to the solid wall thermal conductivity and inversely proportional to vapor pressure and Bond number.
