Note on Evaporation in Capillaries.
Abstract
Factors are discussed which govern evaporation of liquid in small capillaries of greatly varying bore, such as might be encountered in porous media. If the escape of the vapor is relatively unobstructed, marked temperature gradients are found to be confined to close neighborhoods of the menisci. Evaporation is shown to proceed in statically unstable configurations under a dynamic balance of surface tension, local evaporation rate and viscous shear. The larger capillary throats clear first, the smallest ones remain full of liquid. Evaporation rates and fluid velocities are determined approximately.
