Characterization of the near-field flow structure of an acoustically self-excited jet in a large enclosure using particle image velocimetry (PIV)

Creator:: Tobias, Jason A.
Abstract:: An experimental study of the near-field flow structure produced by an incompressible turbulent Acoustically Self-Excited Jet (ASEJ) in a large enclosure using Particle Image Velocimetry (PIV) is presented. The salient feature of this jet is that it provides an increase in near-field mixing and turbulence without additional external power input....

Defining and comparing risks and success measures of the reference design process and traditional new product development processes

Creator:: Larson, Tasha M.
Abstract:: To address aggressive global competition, retain customers and increase revenue, firms are required to pursue New Product Development (NPD) projects. Ventures of this nature are risky and fail often. Numerous factors influence the survival of a project. In this research, 16 factors have been identified and selected as indicators of...

Performance Evaluation of Air Shocks Implemented in a Formula Student Vehicle

Creator:: Fritz, Tim
Abstract:: The Formula Student Team Global Formula Racing from Oregon State University implemented an air suspension system in their 2017 combustion powered vehicle, mainly to save weight. This thesis covers the performance evaluation of such system by comparison to conventional coil over shocks. Utilizing two different Formula Student style courses, three...

Improving Water, Sanitation and Biogas Access in Resource-Stressed Environments : Methodologies and Case Study Analyses of the Primary Resources at Matema Beach High School

Creator:: Richardson, Megan M.
Abstract:: Education as a right has taken off internationally with expanded national policies in recent years. Across Africa over 80% of countries have abolished tuition fees for primary education and several have made the leap to free secondary education as well. With decreased financial barriers keeping kids out of the classroom,...

On the modeling and control of horizontal pendulum wave energy converters

Creator:: Boren, Blake C.
Abstract:: Presented is an investigation into the modeling, active control design, and simulation of a generic horizontal pendulum wave energy converter, known as a PWEC. A description is provided of the dominant attributes PWECs have, showcasing their promising potential as wave energy converters. Seeking to further promote this potential, an active...

Assessing Mass Diffusion Modeling in Premixed Flames

Creator:: Fillo, Aaron J.
Abstract:: Implementing multicomponent diffusion in numerical combustion studies is computationally expensive due to the challenges involved in computing diffusion coefficients. As a result, mixture-averaged diffusion treatments or simpler methods are used to avoid these costs. However, the accuracy and appropriateness of the mixture-averaged diffusion model has not been verified for three-dimensional...

Giant magnetostriction in annealed Co1 − xFex thin-films

Creator:: Hunter, Dwight, Osborn, Will, Wang, Ke, Kazantseva, Nataliya, Hattrick-Simpers, Jason, Suchoski, Richard, Takahashi, Ryota, Young, Marcus L., Mehta, Apurva, Bendersky, Leonid A., Lofland, Sam E., Wuttig, Manfred, and Takeuchi, Ichiro
Abstract:: Chemical and structural heterogeneity and the resulting interaction of coexisting phases can lead to extraordinary behaviours in oxides, as observed in piezoelectric materials at morphotropic phase boundaries and relaxor ferroelectrics. However, such phenomena are rare in metallic alloys. Here we show that, by tuning the presence of structural heterogeneity in...

Numbering-Up of Microscale Devices for Megawatt-Scale Supercritical Carbon Dioxide Concentrating Solar Power Receivers

Creator:: Zada, Kyle R., Hyder, Matthew B., Drost, M. Kevin, and Fronk, Brian M.
Abstract:: Concentrated solar power (CSP) plants have the potential to reduce the consumption of nonrenewable resources and greenhouse gas emissions in electricity production. In CSP systems, a field of heliostats focuses solar radiation on a central receiver, and energy is then transferred to a thermal power plant at high temperature. However,...

Designing and Evaluating a User Interface for Multi-Robot Furniture

Creator:: Stoddard, Brett
Abstract:: A chair, once placed, will stay put until moved. Or will it? With the rise of technology being embeddable into everyday objects, what if that chair could move itself? Such robotic furniture has been featured in advertisements, art, and Human-Robot Interaction (HRI) research. Existing methods for operating robotic furniture have...

Risk- and Reliability-Based Design Optimization in Offshore Renewable Energy Systems

Creator:: Clark, Caitlyn E.
Abstract:: Offshore wind and wave energy have the potential to be significant sources of future global electricity production, reduce carbon emissions, decrease dependence on energy importation, and stimulate economic growth in coastal and remote areas. Fixed-foundation and floating offshore wind and wave energy technologies are at different stages of development, but...
