Small scale laboratory studies of flow and transport phenonmena in pores and fractures, Phase II
Small scale laboratory experiments, equipped with an ability to actually observe behavior on the pore level using microscopy, provide an economical and easily understood scientific tool to help us validateconcepts and assumptions about the transport of contaminants, and offers the propensity to discover heretofore unrecognized phenomena or behavior. The main technique employs etched glass micromodels, composed of two etched glass plates, sintered together, to form a two dimensional network of three dimensional pores. Flow and transport behavior is observed on a pore or pore network level, and recorded on film and video tape. This technique is coupled with related column studies. Specifically we're examining multiphase flow behavior of relevance, for example, to liquid-liquid mass transfer (solubilization of capillary trapped organic liquids); liquid-gas mass transfer (in situ volatilization); colloid movement, attachment and detachment in the presence of fluid-fluid interfaces; bacteria colonization and motility in porous systems; and heterogeneity effects on multi-phase flow, colloid movement and bacteria behavior.
