Understanding capillary condensation and hysteresis in porous silicon: network effects within independent pores.
The ability to exert a significant degree of pore structure control in porous silicon materials has made them attractive materials for the experimental investigation of the relationship between pore structure, capillary condensation, and hysteresis phenomena. Using both experimental measurements and a lattice gas model in mean field theory, we have investigated the role of pore size inhomogenei...
متن کاملCapillary Condensation Hysteresis in Overlapping Spherical Pores:<break></break>A Monte Carlo Simulation Study
The mechanisms of hysteretic phase transformations in fluids confined to porous bodies depend on the size and shape of pores, as well as their connectivity. We present a Monte Carlo simulation study of capillary condensation and evaporation cycles in the course of Lennard-Jones fluid adsorption in the system of overlapping spherical pores. This model system mimics pore shape and connectivity in...

متن کاملCapillary condensation, invasion percolation, hysteresis, and discrete memory.
A model of the capillary condensation process, i.e., of adsorption-desorption isotherms, having only porepore interactions is constructed. The model yields ~1! hysteretic isotherms, ~2! invasion percolation on desorption, and ~3! hysteresis with discrete memory for interior chemical potential loops. All of these features are seen in experiment. The model is compared to a model with no pore-pore...
متن کاملHeat and Mass Transfer with Condensation in Capillary Porous Bodies
The purpose of this present work is related to wetting process analysis caused by condensation phenomena in capillary porous material by using a numerical simulation. Special emphasis is given to the study of the mechanism involved and the evaluation of classical theoretical models used as a predictive tool. A further discussion will be given for the distribution of the liquid phase for both it...
