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)...

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...

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...

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...

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...

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...

Uranium and technetium bio-immobilization in intermediate-scale physical models of an in situ bio-barrier

Creator:: Michalsen, Mandy M.
Abstract:: Metal and hydrogen ion acidity and extreme nitrate concentrations typical of Department of Energy (DOE) legacy waste sites pose formidable challenges to successful implementation of in situ bio-immobilization. Intermediate-scale (~ 2.5 m), flow through models of an in situ bio-barrier were constructed to investigate U and Tc removal from groundwater...

Numerical Investigation of Unsteady Inertial and Turbulent Flows Through Porous Media: Pore-scale DNS, Flow Analyses and Upscaling

Creator:: He, Xiaoliang
Abstract:: Porous media are the materials containing void space or pores, where fluids and gases can pass through. Unsteady flows in porous media are encountered in many engineering applications and natural problems, such as CO₂ sequestration, high temperature nuclear reactor cooling, high efficiency combustion, chemical reactors, noise reduction on airplane trailing...

Exploring the Wettability States and Contact Angle Variation in Porous Media Multi-Phase Flow Systems

Creator:: Behnoudfar, Diba
Abstract:: The wetting of a surface by a liquid is a crucial part of many natural and industrial processes. Despite numerous existing studies, some elements of wetting-dewetting such as contact angle variation are still poorly understood. Knowledge of contact angle behavior during the flow is necessary for modeling fluid displacements in...
