Impact of water vapor diffusion and latent heat on the effective thermal conductivity of snow [PDF]

open access: yesThe Cryosphere, 2021
Heat transport in snowpacks is understood to occur through the two processes of heat conduction and latent heat transport carried by water vapor, which are generally treated as decoupled from one another. This paper investigates the coupling between both

Vapor contribution to the time dependence of the effective diffusion coefficient in partially filled porous glasses [PDF]

open access: yes, 2007
NMR microscopy of silica glasses with micrometer pores (Vitrapor#5) partially filled with water reveal heterogeneous distributions of the liquid on a length scale much longer than the pore dimension.
