CFD simulation of single-phase and flow boiling in confined jet impingement with in-situ vapor extraction using two kinds of multiphase models

Creator:: He, Xiaoliang
Abstract:: With continued development of the electronic industry, the demand for highly efficient heat removal solutions requires innovative cooling technologies. A computational fluid dynamic (CFD) study, including heat transfer, is performed for an axisymmetric, confined jet impingement experiencing boiling and coupled with vapor extraction. Boiling occurs at the target surface while...

Void fraction variations in a fractal-like branching channel network

Creator:: Cullion, Rebecca
Abstract:: Two-phase flow in a fractal-like branching microchannel heat sink may have enhanced heat transfer capabilities over single phase flow in the same branching channel network. In order to exploit this potential, a complete understanding of flow boiling in this geometry is required. The fractal-like geometry is similar to that of...

The leading edge of a tropical instability wave : interpretation as a gravity current

Creator:: McHugh, Elizabeth Helen
Abstract:: A sharp temperature front, oriented along the south-west corner of the leading edge of a Tropical Instability Wave (TIW) warm trough, was encountered at 0°N, 140°W on November 2, 2008 and detected by a 0.45°C increase in SST that occurred over 7 s. The distinct SST signal was observed at...

Black Sermonology and Gospel Music: A Corpus Based Study

Creator:: Horne, Stacey H.
Abstract:: Spirituality is an important component in the lives of many Black Americans. Black American life has spirituality woven into multiple aspects. From what clothes to wear, what words to use when creating a dialogue with others, which television shows to watch, which jobs to pursue, how to treat those who...
Resource Type:: Dissertation

Identifying habitat factors for canary rockfish (Sebastes pinniger) off Washington and Oregon using environmental data and trawl logbooks

Creator:: Vestfals, Cathleen D.
Abstract:: If fisheries managers are to effectively manage commercially exploited fish populations, a basic understanding of the factors that influence fish distribution and abundance is required. In 2005, efforts to identify Essential Fish Habitat (EFH) for the 82 groundfish species managed by the Pacific Fishery Management Council along the West Coast...

Is dam development a mechanism for human security? Scale and perception of the Grand Ethiopian Renaissance Dam on the Blue Nile River in Ethiopia and the Xayaburi Dam on the Mekong River in Laos

Creator:: Veilleux, Jennifer Corinne
Abstract:: Human security is a framework related to the stability and sustainability of political, environmental, economical, and socio-cultural areas of concern. Water resources around the world are under increased pressure from increased development, growing populations, pollution, and global climate change. Large-scale dam development while still popular for political and economic development...

Investigating Timescales of Resurgence at Large Calderas: Post-74 ka Activity at Toba Caldera, Sumatra, Indonesia

Creator:: Mucek, Adonara E.
Abstract:: The Toba Caldera Complex is the youngest resurgent caldera in the last 100 kyrs, formed from four overlapping eruptions starting 1.2 Myrs ago. The last caldera-forming eruption, the Youngest Toba Tuff eruption, occurred ~74 kyrs ago, emitting 2800 km3 of ash and pumice into the atmosphere and forming the caldera...

Modeling rate-limited processes along non-uniform surfaces via the method of volume averaging

Creator:: Lambert, Adam
Abstract:: Quantification of macroscale transport phenomenon in microfluidic systems is important to many science and engineering disciplines. In part, this is because fully resolved solutions to microscale balance laws over large domains are out of reach with current computational technology. Additionally, engineers are most often interested in some upscaled quantity and...

Detection and analysis of separated flow induced vortical structures

Creator:: Snider, Stephen David Louis
Abstract:: Flow separation is an important phenomenon in fluid dynamics because of the effect it has on lift and drag on immersed bodies. Areas of swirl within a separated flow region may have a distinct effect on the surface forces, modifying the lift and drag characteristics. A correlation between the passage...

DNS study of Particle-bed-Turbulence Interactions in Oscillatory Flows

Creator:: Ghodke, Chaitanya Deepak
Abstract:: Turbulent flows over rough surfaces are encountered in many engineering and geophysical applications. Flows of this nature, due to their increasing technological interests, have been a subject of rigorous investigation in recent years. Of the particular interest to the oceanographic community is the study of turbulent oscillatory flow over rough...
Resource Type:: Dissertation
