Cooling System Analysis of the Thrust Chamber

Creator:: Sazonov, Gleb
Abstract:: The purpose of the study was to analyze the possible combination of cooling systems, which are film cooling and regenerative cooling, and obtain the initial estimates of possible temperature reduction. The analysis was conducted in Ansys Fluent. The methodology includes four main steps that are the following: flow simulation, combustion...

Lift Enhancement of Pliant Wings Through Bio-Mimicry

Creator:: Osterberg, Nathaniel Brent
Abstract:: Flexible aerodynamic surfaces have been shown to favorably influence flight characteristics at low Reynolds numbers by increasing lift, angle of attack at stall, and resistance to perturbation. The objective of the research presented within this thesis is to investigate the influence of two aspects of flight observed in biological flyers,...

A study of the stylistic ramifications of Father Charles Edward Coughlin's sermons from 1930 to 1934

Creator:: Acklin, Melissa Barrett
Abstract:: During the depression era, millions of Americans listened to the weekly radio addresses given by Father Charles Edward Coughlin. He devoted his career to speaking out against the evils of America and felt it his duty to warn Americans against the perpetrators of this evil. But after 1934, the tone...

Our Moral Educators : Educational Debate and Representations of Teachers in the Mid-Century Victorian Novel

Creator:: Taylor, Corey
Abstract:: In this thesis, I read the teachers in four mid-century Victorian novels--Charles Dickens' David Copperfield (1850) and Hard Times (1854), Thomas Hughes' Tom Brown’s Schooldays (1857) and Charlotte Brontё's Villette (1853)-- within the context of mid-century English educational debate in an effort to explicate the ways in which these characters...

Turbulent Combustion Analysis of Large Hydrocarbon Fuels in a Reduced Pressure Environment

Creator:: Schorn, Nathan E.
Abstract:: The aviation industry is pushing for better fuels and gas turbine engines for several reasons: cost, emissions, and to a lesser extent high-altitude relights. One aspect that research has been focused on to help reduce costs, emissions and better understand high-altitude relights is studying the combustion behavior of the fuel...

Temperature Evolution of Spark Kernels in Quiescent and Cross-flow Conditions

Creator:: Okhovat, Sebastian
Abstract:: Numerous physical and chemical processes are required for successful ignition of a flammable mixture, many of which have been well characterized. However, one aspect of the ignition process that has received limited consideration is understanding the temperature of the spark kernel. A spark kernel is the volume of heated gas...

Historical Archaeology of Battery Freeman (ca. 1900-1940), Fort Stevens, Oregon

Creator:: Clark, Jorie
Abstract:: This research focuses on events surrounding the activities of Battery Freeman, a coastal defense facility constructed within the earthworks of "old" Fort Stevens near Astoria, OR, in 1900 and destroyed in 1939. Archival data are used in conjunction with nearly 5,000 artifacts that were recovered from archaeological excavations in 1989...

Reverse engineering, modeling, and redesign of a vibratory conveyor

Creator:: Foglesong, Timothy J.
Abstract:: Some successful products are still developed and produced without the benefit of modern design techniques. One such product is a vibratory conveyor that has been developed largely through prototype iteration. The manufacturer has collaborated with Oregon State University to introduce model-based design into the development process. This research details a...

Design analysis using function-based failure propagation in failed system states

Creator:: Jensen, David Charles
Abstract:: For safety critical complex systems, reliability and risk analysis are important design steps. Implementing these analyzes early in the design stage can reduce costs associated with redesign and provide important information on design viability. In the past several years, various research methods have been presented in the design community to...

Thermal and Aerodynamic Effects of Surface Roughness Patterns on Additive Manufactured Heat Sinks

Creator:: Lundeen, Samuel L.
Abstract:: Breakthroughs in heat sink design are now limited by conventional manufacturing techniques which can only produce basic fin shapes with homogenous surface structuring. Additive Manufacturing (AM) is a potential disruptive technology for heat sink design and other convective heat transfer solutions, as surface properties can be directionally varied to maximize...
