Experimental Investigation of the Transition to Natural Convection in HTGR Applications using the Oregon State SFSETF

Creator:: Fishler, Joshua D.
Abstract:: High Temperature Gas Reactors (HTGRs) are positioned to disrupt local and global markets via their unique ability to produce carbon-free process heat, high efficiency power generation, and passively safe operational features. However, significant impediments still exist to delay deployment of this particular technology, including a lack of experimental data, verified...

Investigation of In-tube Non-equilibrium Condensation of Low Global Warming Potential Refrigerants

Creator:: Jacob, Tabeel A.
Abstract:: This work investigates the in-tube condensation of low global warming potential (GWP) zeotropic refrigerant mixtures R448A, R450A, R452A, R454B and R454C. These refrigerants have been proposed for a wide range of commercial heating, ventilation, air-conditioning applications, but their heat and momentum transport phenomenon were not well understood. Thus, in this...

Validation of radiographic automatic exposure control device testing in the era of filmless radiography : and new variables associated with testing

Creator:: Allman, Robert M.
Abstract:: The exposure needed for a clinically useful image requires much less precision when using digital radiography (DR) than when using screen/film (SF) radiography. The Automatic Exposure Control (AEC) device was developed for ensuring accurate and precise exposures with SF technology. This thesis evaluates the importance of the AEC device in...

A multiagent approach to identifying innovation in design components

Creator:: Rebhuhn, Carrie M.
Abstract:: Innovation is a key element for a product to achieve market success, but identifying it within product or even defining the term is a difficult task. Identifying innovation has been approached in many different ways. Experts in design engineering may identify innovative designs based on an analysis of a product's...

Efficiency of a direct contact condenser in the presence of the noncondensable gas air compared to a tube and shell condenser

Creator:: Lebsack, Jonathan M.
Abstract:: Steam distillation is the traditional method used for the extraction of peppermint oil. This process is able to remove approximately 20% of the oils from the leaves of the plant. It is a very costly and un-sustainable process due to the release of carbon emissions. Solvent free microwave extraction promises...

A Permanent-Magnet Linear Generator Wave Energy Converter for Low Power Ocean Sensors

Creator:: Miles, Lillian F.
Abstract:: Renewable energy sources are becoming increasingly important due to their low environmental impact and limitless nature. This thesis explores the design of a 250 mW permanent magnet linear generator wave energy converter to power ocean sensors. While many wave energy converters exist, this is a unique application because the wave...

Reliable Integrated Planning: Applications in Hub Network Design and Airline Ground Crew Task Assignment

Creator:: Barahimi, Pouya
Abstract:: In general, making optimal decisions is a never ending challenge that decision makers face. A comprehensive model that integrates decisions at all three levels of decision making (i.e., strategic, tactical, and operational) can help the decision maker to find solutions that best serve the organization's performance. However, as organizations expand...

A quantitative comparison of cardiovascular imaging systems with respect to the resolution capabilities and the resulting skin entrance doses operating in both fluoroscopic and cine mode

Creator:: Helms, W. Scott
Abstract:: The increasing use of medical procedures using ionizing radiation has increased significantly in recent years. In 1987, the National Council on Radiation Protection Report 93 (NCRP) reported that the average exposure ionizing radiation was 53mRem/year (0.53mSv/year). In their most recent study on radiation exposures NCRP Report 160 in 2009, the...

High Pressure Condensation in an SMR Containment

Creator:: Mullin, Etienne M.
Abstract:: The Oregon State University Multi-Application Small Light Water Reactor test facility is employed in a series tests to evaluate condensation heat transfer in small, high pressure containment vessels characteristic of small modular reactor designs under development. This integral system test facility was constructed to demonstrate the feasibility of a pioneering...

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...
