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...

Surface Water - Groundwater Interactions in Clayey Pasture fields in the WIllamette Valley

Creator:: Gómez, Daniel G.
Abstract:: As the western United States continues to experience prolonged drought that is extending water deficits and threatening ecosystem resilience and socioeconomic systems, it will be vital to understand the relationship between water use and transport for proper water resource management. This is especially important to the agricultural areas of the...

Evaluation of selected marginal aggregates stabilized with cement

Creator:: Chang, Chen
Abstract:: Coastal Oregon is deficient in quality construction aggregate. There is, however, an abundance of lower quality, or marginal aggregate available for construction purposes. The purpose of this report is to develop techniques for upgrading marginal aggregates with portland cement and methods for evaluating the relative performance of these stabilized materials...

Grating-tuned external cavity diode lasers

Creator:: Falconer, Beate Stephan
Abstract:: Diode lasers have many advantages such as small size, high efficiency and small angular dispersion of the collimated beam. However they also have some problems like lack of frequency stability. They can not be tuned in wavelength. An external cavity can solve these problems and decrease the laser linewidth. To...

Proportional integral derivative control of an oil-heated fractal-like branching microchannel desorber

Creator:: Davis, Keith R.
Abstract:: A PID controller was designed to control the performance of an oil-heated fractal-like branching microchannel desorber for use in an ammonia-absorption refrigeration system. Both the amount and concentration of ammonia refrigerant generated at the desorber can be controlled by choosing the rectified circulation ratio as the controlled variable in a...

Weed management for giant reed (Arindo donax) biomass production in Oregon

Creator:: Attarian, Amir
Abstract:: Giant reed (Arundo donax L.) is a candidate to provide feedstock for the Portland General Electric power plant in Boardman, Oregon. Giant reed is a fast perennial grass, producing 23-27 metric tons ha⁻¹ of biomass and has the ability to adapt to diverse environments making it a good candidate for...

Integrated dual cycle energy recovery using thermoelectric conversion and an organic Rankine bottoming cycle

Creator:: Miller, Erik W.
Abstract:: Hot engine exhaust and industrial process exhaust represents a resource that is often rejected to the environment without further utilization. This resource is prevalent in the transportation and industrial process sectors, but stationary engine-generator systems also typically do not utilize this resource. Engine exhaust is considered high grade heat and...

A quantitative structure activity relationships study of antiinfectives based on the nalidixic acid structure

Creator:: Yu, Yupei
Abstract:: Nalidixic acid and its derivatives act through inhibition of bacterial DNA gyrase activity. Recently there have been a series of papers reporting the antibacterial activity against three different types of bacteria (S. aureus, E. coli and P. aeruginosa) by a series of 1,4-dihydro-4-oxoquinoline (or 1,8-naphthyridine) 3-carboxylic acids. Consistent biological data...
