Summary

A microscopic model for drying capillary porous medium is presented in this thesis. This microscopic model is based on a network approach to the porous medium and is used to study the drying behavior of the porous medium inside during the drying process scale pores. The driving force for liquid transport is the capillary force and mass transfer in the gas phase and the vapor diffusion. The Kelvin effect is considered in this model, that is, the gas-liquid interface is treated as a meniscus. The gravitational force is ignored because the sizes and pore throats network are relatively large (> 20mm). The drying process is simulated using this model on several square networks 100x20 containing pores 2000 and 4000 throats. The liquid is alcohol and the isothermic drying process is assumed.
