On existence and uniqueness of weak solutions to the Navier-Stokes equations in R3

Creator:: Peterson, Samuel H.
Abstract:: This thesis is on the existence and uniqueness of weak solutions to the Navier-Stokes equations in R3 which govern the velocity of incompressible fluid with viscosity ν. The solution is obtained in the space of tempered distributions on R3 given an initial condition and forcing data which are dominated by...

A study of micro-scale, fractal-like branching flow networks for reduced pumping power and improved temperature uniformity

Creator:: Alharbi, Ali Y.
Abstract:: A first generation, one-dimensional predictive model is proposed for designing heat sinks with fractal flow networks. A three-dimensional computational fluid dynamics (CFD) model is analyzed as a means for validating the model and identifying areas for improvement. Two separate CFD models were developed. One was analyzed with conjugate heat transfer...

Investigating climate feedbacks across forcing magnitudes and time scales using the radiative kernel technique

Creator:: Jonko, Alexandra
Abstract:: Radiative feedbacks associated with changes in water vapor, temperature, surface albedo and clouds remain a major source of uncertainty in our understanding of climate's response to anthropogenic forcing. In this dissertation climate model data is used to investigate variations in feedbacks that result from changing CO₂ forcing and the time...

Investigation of Destratification in Warehouses

Creator:: Polander, Michael D.
Abstract:: A significant source of energy consumption comes from maintaining desired indoor environment conditions in warehouses and other industrial facilities. In efforts to combat the raising energy costs, studies into more efficient heating and cooling strategies has been a topic of consideration for a number of years. One of the areas...

Dynamical System Scaling of Fuel Performance During Reactivity Insertion Accidents

Creator:: Dueñas, Alexander M.
Abstract:: Fuel qualification timelines for new fuel technology under ideal conditions can take between 20-25 years to be fully qualified from initial concept to deployment as full fuel assemblies. To reduce the timeline and costs, new separate-effects test and integral-effects test experiments, advanced instrumentation, and advanced modeling and simulation tools are...

The development and evaluation of an interactive exhibit to support real-time water quality data interpretation by the public at an informal education setting

Creator:: Mikulak, Sarah E.
Abstract:: Ocean observing groups are currently making efforts to work with well-defined end-user groups, like boaters and fishermen, to provide meaningful and effective real-time data (RTD) products and visualizations. However, providing meaningful data products for undefined groups such as the general public is not straightforward. In Oregon, several industry, science, and...

Preliminary Numerical Study of a Condenser Using Fractal-Like Patterned Hydrophobic and Hydrophilic Strips

Creator:: Lazaroff, Spencer A.
Abstract:: Condensers are vital components of power plants and are often one of the most major cost concerns when planning construction. Generally speaking, the surface area required to dissipate the heat generated in the boiler is so great that enormous and expensive structures are necessary. The usage of a hybrid surface...

Investigation of volumetric coupling effects on particle-laden turbulent flows at dilute to moderate loadings

Creator:: Cihonski, Andrew John
Abstract:: Particle-laden turbulent flows are of great importance in many industrial applications and are sufficiently complex to require multiple methods of study to provide a better understanding of the dominant physical mechanisms present in these processes. This work on large-eddy simulation of particle-laden flows seeks to help provide the building blocks...

Application of biomarker compounds as tracers for sources and fates of natural and anthropogenic organic matter in the environment

Creator:: Oros, Daniel R.
Abstract:: Determination of the source and fate of natural (higher plant lipids, marine lipids, etc.) and anthropogenically (e.g., petroleum, coal emissions) derived hydrocarbons and oxygenated compounds in the environment was accomplished using gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) to characterize or identify molecular biomarkers to be utilized as tracers....
