Microscale thermal management using membrane vapor extraction

Creator:: Apreotesi, Mario A.
Abstract:: With the miniaturization of microelectronics and increase of processor speeds in the last few decades, thermal management is drastically affecting overall packaging and system capabilities. Due to the special needs introduced, research focusing on microscale cooling has increased. This study combines the positive characteristics of single- and two-phase flows in...

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...

Contribution of cold seep barite to the barium geochemical budget of a marginal basin

Creator:: McQuay, Erica L.
Abstract:: Large barite (BaSO4) structures mark cold seeps in the southern San Clemente Basin. Barium flux to San Clemente sediments is two to three times greater than fluxes measured in surrounding California Borderland basins. Analyses of sediment trap material, water column samples, sediments and pore water indicate that expected bariumbearing mineral...

Preliminary Numerical Study of a Condenser Using Fractal-Like Patterned Hydrophobic and Hydrophilic Strips

Creator:: Lazaroff, Spencer A.
Abstract:: Condensers are vital components of power plants and are often one of the most major cost concerns when planning construction. Generally speaking, the surface area required to dissipate the heat generated in the boiler is so great that enormous and expensive structures are necessary. The usage of a hybrid surface...

Freeze Stage Analysis of an Indirect Freeze Desalination System

Creator:: Whitaker, Trevor A.
Abstract:: Freeze desalination poses as a potential solution to many of the issues that accompany current desalination methods. The research detailed in this manuscript involves creating and analyzing a numerical model of the freezing operation of an indirect contact freeze-melting (FM) desalination system. In this initial analysis, pure water is frozen...

A multiscale modeling approach for bubble-vortex interactions in hydro-propulsion systems

Creator:: Finn, Justin Richard
Abstract:: Multiphase flow dynamics are important in many naval and turbomachinery applications, where bubble interaction with low pressure, vortical structures can lead to undesirable cavitation effects. To better understand the underlying phenomena, a multiscale numerical framework is developed to simulate bubble laden flow in dynamic hydro propulsion systems. Several subproblems in...

Nonlinear model reduction using the group proper orthogonal decomposition method

Creator:: Dickinson, Benjamin T.
Abstract:: Proper orthogonal decomposition (POD) in conjunction with the Galerkin projection has been used as a model reduction technique for the tractable real-time control of high-dimensional systems. While POD based model reduction may improve the tractability of high-dimensional models, the nonlinear POD based model may be impractical for control due to...

An experimental study of co-flow ammonia-water desorption in an oil-heated, microscale, fractal-like branching heat exchanger

Creator:: Mouchka, Gregory A.
Abstract:: An experimental study was performed in which an ammonia-water solution was desorbed within a branching fractal-like microchannel array. The solution entered in the center of a disk, and flowed out radially until discharging in to a gravity-driven separation chamber. Heat was added to the ammonia-water through a thin wall, above...

Development of a Cartesian-grid-based solver for an oscillatory boundary layer over a rough wall

Creator:: Skitka, Joseph M.
Abstract:: Predominant models for predicting rates of sediment transport face acute shortcomings when applied to coastal boundary layers. This is due to a neglect of the web of stochastic variables governing the rate of sediment dislodgement. While stochastic models do exist, the parametric extent of their validity tends to be limited,...

Shear and convective turbulence in a model of thermohaline intrusions

Creator:: Mueller, Rachael
Abstract:: Thermohaline interleaving is an important mechanism for laterally fluxing salt, heat, and nutrients between oceanic water masses. Interleaving is driven by a release of potential energy resulting from the vastly differing diffusivities of heat and salt in seawater. The flows are composed of stacked intrusions that flux more buoyant and...
