Modeling of Evaporation from Nanopores with Nonequilibrium and Nonlocal Effects

Evaporation from nanopores is of fundamental interest in nature and various industrial applications. We present a theoretical framework to elucidate evaporation and transport within nanopores by incorporating nonequilibrium effects due to the deviation from classical kinetic theory. Additionally, we include the nonlocal effects arising from phase change in nanoporous geometries and the self-regulation of the shape and position of the liquid–vapor interface in response to different operating conditions. We then study the effects of different working parameters to determine conditions suitable for maximizing evaporation from nanopores.
