Capillary stresses in disordered unsaturated porous materials

Capillary condensation in disordered porous materials - specifically, the interplay of spatial distribution of grains/pores, temperature and distribution of capillary stresses - is explored. This is achieved through lattice gas density functional theory and a recently proposed method for computing capillary stresses based on equivalency of lattice and phase field fluid models in the continuum limit. Gaining insights into the distribution of capillary stresses at a given relative humidity and temperature in disordered porous materials pave the way for fluid mixture coupling with solid deformation while enriching current methods for inferring pore size distribution and pore connectivity from adsorption/ desorption experiments.
