Problems of Shape and Information in Multiscale Modeling of Transport Phenomena

Creator:: Ostvar, Sassan
Abstract:: This work is a compilation of problems that deal with multiscale analysis of transport phenomena in environmental systems. A common feature among the problems studied here is the presence of non-negligible microscale structure in various forms. Each problem is approached from the perspective that a macroscopic observable encodes aspects of...

Investigation of transport phenomena in a highly heterogeneous porous medium

Creator:: Vogler, Daniel
Abstract:: This work focuses on solute mass transport in a highly heterogeneous two-region porous medium consisting of spherical low-hydraulic conductivity inclusions, embedded in a high-hydraulic conductivity matrix. The transport processes occuring in the system are described by three distinct time scales. The first time scale reflects the characteristic time for convective...

Development of a binary mixture gas composition instrument for use in a confined high temperature environment

Creator:: Cadell, Seth R.
Abstract:: With recent advancements in material science, industrial operations are being conducted at higher and higher temperatures. This is apparent in the nuclear industry where a division of the field is working to develop the High Temperature Gas Reactor and the Very High Temperature Gas Reactor concurrently. Both of these facilities...

Steady-State Diffusion in a Spatially Varying Porous Medium

Creator:: Ferrero, Peter T.
Abstract:: Heterogeneous porous material represents a persistent challenge in the field of engineering. Microscale properties such as the porosity and microchannel torturosity significantly control the macroscale transport characteristics of homogeneous porous medium. Additional complexity is introduced when these small-scale features vary in space. Examples of heterogeneous porous systems include artificial body...

Determination of local material properties of OSB sample by coupling advanced imaging techniques and morphology-based FEM simulation

Creator:: Sebera, Vaclav and Muszynski, Lech
Abstract:: The goal was to determine local mechanical properties inside of oriented strand board (OSB) based on a realistic morphology-based finite element (FE) model and data acquired from a physical test performed on the same material. The spatial information and local grayscale intensity from CT-scans obtained from small OSB sample was...

Consumer perceptions of decking material

Creator:: Thomas, Jon M.
Abstract:: Wood remains the most popular material for deck construction. For centuries, consumers have chosen wood because of its desirable qualities and aesthetics. In recent years, wood plastic composites (WPC's) have seen rising demand as alternatives to wood decks, despite a large price premium. In addition, the removal of CCA treated...

U(VI) transport in subsurface materials: is two-site, one-species modeling sufficient?

Creator:: Harrington, Stephanie J.
Abstract:: Uranium adsorption to Hanford sediment was studied for various pH, total inorganic carbon concentrations, and total U(VI) concentrations. Both batch and transport studies were done in an attempt to understand the adsorptive trend of U(VI) on Hanford sediment, and the changes in adsorption as both pH and total inorganic carbon...

Sustainable bio-composites for highway infrastructure: Feasibility of material substitution in existing products

Creator:: Karas, Michael and Muszynski, Lech
Abstract:: The U.S, Forest Service regularly removes tons of dead biomass from federal forestlands to control and prevent devastating wildfires. Every year thinning young trees and brush, as well as removing dead biomass from the forest floor generates large quantities of low-grade woody material for which there is little use. Currently...
