FLUID-PHASE MORPHOLOGIES INDUCED BY CAPILLARY PROCESSES IN POROUS-MEDIA

A topological analysis of the phase- filled state of ''sites'' (cavities, antrae) and ''bonds'' (passages, windows), is presented graphically for several capillary processes in porous media. The originalities of this treatment consist in: (i) fundamental and technical aspects of the simulation of porous media, allowing topological size- correlations between neighbouring network elements, and (ii) consideration of menisci cooperative behaviour according to local network geometry and appropriate physical constraints for each process.
