Analyzing the Relationship between Capillary Pressure, Saturation, and Interfacial Area for a Three-Phase Flow System in Porous Media

Creator:: Paustian, Rebecca L.
Abstract:: Multi-phase flow in porous media includes many instances of subsurface flow. Three-phase flow in particular is important in situations of enhanced oil recovery, CO2 sequestration, and groundwater remediation. Many studies have been performed on how two fluid phases (oil/water or air/water) behave in porous media, but very few studies exist...

Numerical simulation of anaerobic reductive dechlorination of CAHs in continuous flow systems

Creator:: Mustafa, Nizar Ahmad
Abstract:: Halogenated organic compounds have had widespread and massive applications in industry, agriculture, and private households, for example, as degreasing solvents, flame retardants and in polymer production. They are released to the environment through both anthropogenic and natural sources. The most common chlorinated solvents present as contaminants include tetrachloroethene (PCE, perchloroethene)...

Measurement of Gas Exchange, Stream Metabolism, and Carbon Fluxes of Headwater Streams

Creator:: Pennington, Robert S.
Abstract:: Freshwater systems are an important component of the global carbon cycle as they outgas disproportionately large quantities of carbon compared to the terrestrial landscape. Of particular importance are headwater streams, which represent roughly 90% of the channel network by length and have been conservatively estimated to outgas roughly 36% of...

Solution of the 2D quasi-diffusion low-order equations using a coupled nodal/finite volume discretization in Cartesian and hexagonal geometry

Creator:: Nes, Razvan
Abstract:: An important improvement in the area of reactor core neutronic modeling is the development and use of the methods based on "quasi-diffusion" (QD) low-order equations. This family of methods takes into account the transport exactly using "functionals" computed by solving transport equations, and is amenable to solution with a variety...

Investigating capillary pressure and interfacial area for multiphase flow in porous media using pore-scale imaging and lattice-Boltzmann modeling

Creator:: Porter, Mark L.
Abstract:: Recent advances in imaging technology and numerical modeling have greatly enhanced pore-scale investigations of multiphase flow and transport in porous media. It is now feasible to obtain high resolution 3-dimensional pore-scale data, and numerical methods such as the lattice- Boltzmann (LB) technique have been developed specifically for simulating such phenomena....

Development of a Field Arsenic Test Utilizing PEG Functionalized Gold Nanoparticles

Creator:: Patel, Kian
Abstract:: Arsenic in its inorganic form is naturally present in groundwater. Continued exposure to arsenic contaminated water can result in long lasting health complications, ranging from cognitive development issues to cancer. One method which may be convertible to a field test is the use of PEG functionalized gold nanoparticles which aggregate...

A Graph Grammar Representation of Metal-Organic Frameworks for Computational Synthesis and Exploration

Creator:: Geringer, Mark K.
Abstract:: In this work, metal-organic frameworks (MOFs) are computationally represented, generated, and evaluated. The organic linker molecules are represented as graphs and use graph grammars where the atoms are represented by nodes and the bonds are represented by arcs. The grammar rules that dictate the graph generation process work on the...

Thermodynamic correction for salts in variably saturated porous media

Creator:: Burns, Erick R.
Abstract:: Using thermodynamic principles, the general relationship describing the equilibrium vapor content in the gas phase above a saline liquid and across a curved liquid-gas interface is developed. Since high salt concentration also affects the intensive and extensive liquid properties, it is also necessary to account for these effects in liquid...

Flow processes in the dry regime : the effect on capillary barrier performance

Creator:: Jansik, Danielle P.
Abstract:: Engineered capillary barriers typically consist of two layers of granular materials designed so that the contrast in sediment hydrologic properties and sloping interface retains infiltrating water in the upper layer. We report here on the results of two bench-top capillary barrier experiments, and associated modeling. These experiments were conducted to...

Evaluation in a Physical Aquifer Model the Long-Term Performance of a Permeable Reactive Bio-Barrier Packed with Co-encapsulated Gellan Gum Beads for the Bioremediation of Chlorinated Compounds and Co-Contaminants

Creator:: Wortkoetter, Jacob
Abstract:: Chlorinated solvents are a class of widespread groundwater contaminants that are toxic, carcinogenic, and difficult to remediate at low concentrations. 1,4-dioxane, a suspected carcinogen, is often a co-contaminant found in mixtures of chlorinated solvent plumes. In-situ bioremediation methods of degrading these chemicals through aerobic cometabolism have shown promise. Permeable Reactive...
