Pore network model of drying with Kelvin effect

A pore network model of isothermal drying is presented. The takes into account the capillary effects, transport vapor by diffusion, including Knudsen effect, in gas phase, and Kelvin effect. seen as a first step toward simulation mesoscopic porous materials involving sizes between 4 nm 50 nm. major issue addressed with present computation menisci mean curvature radius at boundary each liquid cluster conjunction impact effect on process investigated, varying relative humidity ambient air outside medium. simulations indicate that has significant distribution during drying. evaporation rate found to fluctuate due variations also highlight noticeable non-local equilibrium
