PHASE DETERMINISTIC MODELING OF WATER-VAPOR RETENTION IN POROUS MEDIA AND ITS POTENTIAL IN UNSATURATED FLOW APPLICATION

Yu Wang
University of Salford

RÉSUMÉ

A recent proposed physical-chemical model for the static water retention characteristic of porous media has been further studied for a profound exploring of its underlying physics. This note presents an investigation that yields a general deterministic formula for the water retention characteristic of porous media. Based on the new development, a former simplified fitting model is revised. Both of the deterministic formula and the improved fitting model are tested to model the water retention curve of different porous materials. At the end, the potential advantage of the deterministic formula is discussed for application in dynamic unsaturated flow analysis.
