Toward a Molecular-Scale Understanding of Chemical Adsorption and Frost Heaving: Phase II
Abstract
Significant advances were made in three basic areas: (1) Multiscale flow and deformational of swelling porous media, (2) nonlocal transport of contaminants in porous media, and (3) development of a molecular-scale understanding of phase separation in binary fluids in microporous media. Two- and three-scale theories were developed for fluid flow and chemical transport in expansive media such as natural soils and many biopolymers. The balance laws coupled with novel constitutive theories were implemented computationally and then compared (favorably) to experimental results. The first successful simulation of crust formation was presented. Chemical transport theories for porous media with evolving heterogeneity were developed. The theories were nonlocal in space and time. They were numerically implemented and they compared favorably to field experiments. Numerical statistical mechanical Monte Carlo simulations of binary mixtures in corrugated micropores were reported. Novel examples of strain induced liquefaction, chromatography and phase coexistence were presented. One book and 20 referred papers were published based on these efforts.
