Numerical design of a high-flux microchannel solar receiver

Creator:: Rymal, Charles
Abstract:: This thesis discusses the design of several microchannel solar receiver devices for use in CSP (concentrated solar power) using CFD (computational fluid dynamics) simulations. The goal is to demonstrate that, by taking advantage of the higher heat transfer coefficienct of microchannels, solar receivers can achieve higher efficiency than current receiver...

Bioenergetics and behavior of the krill Euphausia pacifica in the California Current System off the Oregon coast

Creator:: Lindsey, Brie J.
Abstract:: Euphausia pacifica, the North Pacific krill, is a key grazer in the California Current System and an important prey item for consumers such as salmon, seabirds, and whales. As a crucial link between phytoplankton and higher trophic levels, it is essential to understand both the behavior and bioenergetics of this...

Assessment of the potential for conflict between existing ocean space use and renewable energy development off the coast of Oregon

Creator:: Sullivan, Colleen M.
Abstract:: Oregon's ocean waters are a potential source of wind, wave, and tidal energy; of interest to renewable energy entrepreneurs and to the U.S. government as it seeks to bolster energy security. In order to install technology to capture this energy, however, it may be necessary to mitigate conflict with existing...

Local heat transfer rate and bubble dynamics during jet impingement boiling

Creator:: Mani, Preeti
Abstract:: Characterization of local boiling trends, in addition to the typically reported area-averaged trends, is essential for the robust design and implementation of phase change technologies to sensitive heat transfer applications such as electronics cooling. Obtaining the values of heat fluxes corresponding to locally varying surface temperatures has been a challenge...

Ecology of Greenland halibut (Reinhardtius hippoglossoides) during the early life stages in the Eastern Bering Sea and Aleutian Islands

Creator:: Sohn, Dongwha
Abstract:: Greenland halibut (Reinhardtius hippoglossoides) have decreased in the eastern Bering Sea and Aleutian Islands since the 1970s. The reasons behind the poor recruitment are unknown, and important knowledge gaps of the ecology of the early life stages have been identified. The objectives of thesis research were (1) to examine geographic...

A Geometric Morphometric Analysis of Projectile Point Maintenance using Experimental Resharpening Techniques: An Examination of PFP1 Curation, Cooper’s Ferry Site, Idaho

Creator:: Skinner, Sarah M.
Abstract:: The incorporation of experimental archaeology into the study of lithic technologies has provided archaeologists with a framework to understand past behaviors. The analysis of stone tools has the potential to reveal morphologic characteristics unique to the manufacture, use, and maintenance of stone tools. The implementation of controlled experiments to identify...

Remineralization of marine particulate organic matter

Creator:: Burkhardt, Brian Gary
Abstract:: Marine microorganisms play a significant role in the cycling of nutrients in the open ocean through production, consumption, and degradation of organic matter (OM). Carbon (C), nitrogen (N), and phosphorus (P) are essential ingredients in every known recipe for life. However, the cycling of each of these elements proceeds at...

Application of digital image correlation in material parameter estimation and vibration analysis of carbon fiber composite and aluminum plates

Creator:: Chuang, Chih-Lan Jasmine
Abstract:: Identifying material parameters in composite plates is a necessary first step in a variety of structural applications. For example, understanding the material parameters of carbon fiber composite is important in investigating sensor and actuator placement on micro-air-vehicle wings for control and wing morphing purposes. Knowing the material parameters can also...

Transport of the copepod, Calanus finmarchicus, in the northwest Atlantic during diapause

Creator:: Kowalke, Gregory L.
Abstract:: The copepod Calanus finmarchicus is the most important and biomass dominant mesozooplankter in the temperate-boreal North Atlantic. C. finmarchicus has an overwintering phase, termed diapause, during which it descends to great depths (300-2000m) and is metabolically quiescent for up to ten months. Changes in the currents at depth due to...

Leading Edge Separation Analysis of Oscillating Airfoil Energy Harvesters

Creator:: Ngo, Vickie
Abstract:: Oscillating foil energy harvesters are analyzed at optimal reduced frequencies (𝑘=𝑓𝑐/𝑈) to determine how the leading edge radius of curvature affects leading edge separation. The understanding of leading edge separation and its behaviors is critical to predicting the transient lift profile of an airfoil. The separation is therefore also critical...
