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...

Two-Color Laser Induced Fluorescence Imaging of Fluid Temperature for Free Convection and Vapor Condensation

Creator:: McAfee, Rachel
Abstract:: The development of a continuous and reliable cooling method for computer chips is an evolving subject requiring continuous research in both computer science and thermal management. Two-color laser induced fluorescence (LIF) provides a non-invasive way to investigate electronics cooling fluid behavior. Dielectric fluids are of particular interest as they allow...

An Evaluation of Onboarding and Training Procedures of Oregon State University County Extension Faculty

Creator:: Knight, Kelsey J.
Abstract:: Oregon State University Extension employs county-based Extension Faculty to deliver educational programs to communities across the state. County Extension Faculty are expected to be competent in various content and training can help prepare faculty for the profession. Using a needs assessment approach, this research evaluated the training available. The results...

Automating aquatic insect identification through pattern recognition

Creator:: Thomas, Joshua K.
Abstract:: Aquatic insect population counts can be a good indicator of the health, or water quality, of rivers and streams. Stoneflies (Plecoptera) are particularly susceptible to pollution in streams. However, today’s current method for obtaining these population counts requires biologists to examine individual specimens under a microscope for identification to the...

Validation Analysis for the OSU HTTF PG-28 Test Using RELAP5-3D and STAR-CCM+

Creator:: Halsted, Joshua K.
Abstract:: High temperature gas reactors (HTGR’s) have been researched and operated commercially since the inception of the nuclear industry. Newer designs, such as the General Atomics (GA) Modular HTGR, aim to lower capital costs by shifting towards smaller, more modular designs, although further cost reductions with respect to operations and maintenance...

Influence of diagonal cracks on negative moment flexural anchorage performance in reinforced concrete bridge girders

Creator:: Goodall, Joshua K.
Abstract:: Large numbers of vintage reinforced concrete deck-girder bridges remain in the national bridge inventory. Many of these exhibit diagonal cracking and other distress. Due to the design practices of the time, it is common to observe cracks at locations where flexural reinforcing steel is terminated along the span. The presence...

Habitat relationships of native and non-native fishes of the Willamette River, Oregon

Creator:: Williams, Joshua E.
Abstract:: The Willamette River flows north between the Cascade Mountains and Coast Range of western Oregon within a 29,728-km² basin. The fish community in the geologically young basin consists of 36 native species, but introductions of non-native fishes have added 33 additional species for a total of 69 fish species. During...

Division algebra representations of SO(4,2)

Creator:: Kincaid, Joshua James
Abstract:: Representations of SO(4,2;R) are constructed using 4 x 4 and 2 x 2 matrices with elements in H' ⊗ C . Using 2 x 2 matrix representations of C and H', the 4 x 4 representation is interpreted in terms of 16 x 16 real matrices. Finally, the known isomorphism...

Verification & Analysis of RELAP5-3D Code Modeling Diffusive Air Ingress Methods and Their Effects on Natural Circulation Time

Creator:: Schlamp, Nicklaus K.
Abstract:: The Energy Policy Act of 2005 dictates that the Nuclear Regulatory Commission (NRC) in conjunction with the Department of Energy (DOE) are responsible for the licensing and regulation safety strategies of the Very High Temperature Gas-cooled Reactor (VHTGR). The VHTGR is a next generation nuclear design that is capable of...

CFD Verification, Validation, and Sensitivity Study of Internally Heated Concentric Tube Thermosyphon O-SERTTA

Creator:: Miller, Jaden
Abstract:: Irradiation experiments are a critical aspect of the nuclear fuels and materials qualification process. Determining the flow conditions of these experiments is necessary for understanding response of nuclear components during transient and normal operation. Quality flow data is lacking for cartridge-type irradiation experiments with annular flow natural circulation designs. Data...
