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...

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...

The Use of Fractal-Like Bifurcating Flow Channels for Biological Targeted Cooling

Creator:: Stottlemyre, Wyatt
Abstract:: In the wake of climate change, the risk of heat related illnesses has continuously increased over the past several decades. While thermal management solutions have continued to improve, there is a need for efficient cooling systems that conform with the human body. This study combines the solutions from fractal-like flow...

RANS and LES predictions of turbulent scalar transport in dead zones of natural streams

Creator:: Drost, Kevin J.
Abstract:: Natural stream systems contain a variety of ﬂow geometries which contain ﬂow separation, turbulent shear layers, and recirculation zones. This work focuses on streams with dead zones. Characterized by slower ﬂow and recirculation, dead zones are naturally occurring cutouts in stream banks. These dead zones play an important role in...

Modeling of Non-Spherical Particle Dynamics in a Non-Uniform Flow

Creator:: Alshehri, Ahmad S.
Abstract:: Turbulent flow with suspended, non-spherical particles can be found in nature and several industrial applications. Although turbulence with dispersed spherical particles has been studied extensively, modeling the dynamics of non-spherical particles in a turbulent flow has not been studied extensively. Motion of spherical particles in complex flows is typically captured...

A study of micro-scale, fractal-like branching flow networks for reduced pumping power and improved temperature uniformity

Creator:: Alharbi, Ali Y.
Abstract:: A first generation, one-dimensional predictive model is proposed for designing heat sinks with fractal flow networks. A three-dimensional computational fluid dynamics (CFD) model is analyzed as a means for validating the model and identifying areas for improvement. Two separate CFD models were developed. One was analyzed with conjugate heat transfer...

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...

Investigation of volumetric coupling effects on particle-laden turbulent flows at dilute to moderate loadings

Creator:: Cihonski, Andrew John
Abstract:: Particle-laden turbulent flows are of great importance in many industrial applications and are sufficiently complex to require multiple methods of study to provide a better understanding of the dominant physical mechanisms present in these processes. This work on large-eddy simulation of particle-laden flows seeks to help provide the building blocks...

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,...
