A Multilevel Nonlinear Projective Method for Circulating Fuel Reactor Kinetics

Creator:: Reynolds, Aaron J.
Abstract:: Circulating fuel reactor (CFR) kinetics are characterized by delayed neutron precursor (DNP) drift in addition to the neutronic and thermal hydraulic phenomena typical of other reactor types. This environment can be computationally challenging to model, given that the multiphysics phenomena generally have non-linear interdependencies requiring the use of iterative solution...

Life History of the Northern Rubber Boa (Charina bottae) in Oregon

Creator:: Leppin, Mark V.
Abstract:: The Northern Rubber Boa (Charina bottae) is a small, secretive boa native to the Pacific Northwest. Despite this being possibly the highest latitude boas and one of only two boas native to the continental U.S., it has received surprisingly little attention. Most of the research on the natural history of...

The Grizzly Bear and the Deer : the history of Federal Indian Policy and its impact on the Coast Reservation tribes of Oregon, 1856-1877

Creator:: Van Laere, M. Susan
Abstract:: The Coast Reservation of Oregon was established under Executive Order of President Franklin Pierce in November, 1855, as a homeland for the southern Oregon tribes. It was an immense, isolated wilderness, parts of which had burned earlier in the century. There were some prairies where farming was possible, but because...

Modeling and simulation of volume displacement effects in multiphase flow

Creator:: Cihonski, Andrew John
Abstract:: There are many options available when selecting a computational model for two-phase flows. It is important to understand all the features of the model selected, including when the model is appropriate and how using it may affect your results. This work examines how volume displacement effects in two-phase Eulerian-Lagrangian models...

On the Euler-Lagrange Modeling of Particle-laden Turbulent Flows

Creator:: Pakseresht, Pedram
Abstract:: Particle-laden turbulent flows, wherein a large number of small size particles are dispersed in a fluid, are widely encountered in environmental and industrial applications. Understanding their underlying physics, making predictions without performing expensive experiments, and ultimately optimizing the systems carrying such flows, require accurate and robust modelling tools. The Euler-Lagrange...

Detection and analysis of separated flow induced vortical structures

Creator:: Snider, Stephen David Louis
Abstract:: Flow separation is an important phenomenon in fluid dynamics because of the effect it has on lift and drag on immersed bodies. Areas of swirl within a separated flow region may have a distinct effect on the surface forces, modifying the lift and drag characteristics. A correlation between the passage...

Modelling Thin Liquid Film Draining of Bubbles on Porous Media in Confined Geometry

Creator:: Bahm, Jared S.
Abstract:: The behavior of the thin liquid ﬁlm formed between a bubble and hydrophobic membrane is of high interest in applications where separating two-phase mixtures is beneﬁcial. One such application is in-situ vapor extraction heat sinks. In these systems, high heat transfer rates are accomplished by taking advantage of the high...

Biogeochemical signals of mountainous forested watersheds' response to disturbance

Creator:: Guerrero-Bolaño Francisco J.
Abstract:: Small mountainous watersheds are disproportionate sources of land-derived particulate organic matter (POM) to long-term sinks like lake bottoms and the ocean. As such, these ecosystems are an essential component of the global carbon cycle. The burial of POM in lacustrine and marine sediments contributes to the drawdown of atmospheric CO2...

Advancing Understanding of Changes in the Cryosphere of the Western United States and Alaska: A Case for the Importance of Spatial and Temporal Scaling

Creator:: Roberts-Pierel, Benjamin M.
Abstract:: The global cryosphere, defined as the world’s ice and snow covered regions, is a crucial water source for society and ecosystem functions, as well as an important regulator of the earth’s energy budget. Melt from glaciers and seasonal snow cover provides water for more than a sixth of the world’s...

Development of a Cartesian-grid-based solver for an oscillatory boundary layer over a rough wall

Creator:: Skitka, Joseph M.
Abstract:: Predominant models for predicting rates of sediment transport face acute shortcomings when applied to coastal boundary layers. This is due to a neglect of the web of stochastic variables governing the rate of sediment dislodgement. While stochastic models do exist, the parametric extent of their validity tends to be limited,...
