Development of a process for fabricating high-aspect-ratio, meso-scale geometries in stainless steel

Creator:: Walker, Benjamin A.
Abstract:: Miniature energy and chemical systems (MECS) are miniature thermal, fluid, and chemical devices in the mesoscale size range between a sugar cube and a human fist. MECS take advantage of improved rates of mass and heat transfer that have been observed at the microscale. There are many potential applications for...

Effect of vibration on forced convection to water from a cylinder at Reynolds numbers in the range of stable vortex shedding

Creator:: Graves, Donald Larry
Abstract:: An experimental investigation has been made of the effect of vibration on heat transfer from a cylinder in crossflow. The cylinder used was 3/16-inch in diameter and was sinusoidally oscillated in the vertical direction by a mechanical drive mechanism while immersed in an open water channel. Nominal amplitude ratios, a/d,...

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...

A comparative study of the performance of pin finned heat sinks for cooling electronic components by natural convection

Creator:: Manolescu, Mircea Ion
Abstract:: A study was conducted to determine the heat transfer characteristics of pin finned heat sinks in natural convection. Three pin diameters were studied: 0.238 cm, 0.318 cm and 0.396 cm. The pins were attached to the base in two arrangements, triangular and rectangular, forming a horizontal array. Pin spacing was...

Spatio – temporal temperature variations during droplet impingement evaporation : effects of nanofluid and nano-structured surface

Creator:: Graber, Christof
Abstract:: Droplet and spray impingement cooling are typically used in high heat flux thermal management. In this thesis, droplet impingement and evaporation heat transfer characteristics are determined from measured spatially- and temporally- varying fluid and surface temperatures. Unique to this study is the documentation of the effects of using a nanofluid...

A thermal hydraulics analysis of a molybdenum production element for implementation in TRIGA reactors

Creator:: Byfield, Patrick
Abstract:: The metastable isotope of technetium-99 (Tc-99m) is an important diagnostic tool used in the field of nuclear medicine due to the isotope's 6.0 hour half-life, 140.5 keV γ-decay mechanism, and multiple oxidation states [1,2]. Approximately 70% of the world’s nuclear medicine procedures involve the use of Tc-99m [3]. The conventional...

Scaling analysis of the Direct Reactor Auxiliary Cooling System for Gas-cooled Fast Reactors during a Depressurized Loss of Forced Convection Event

Creator:: Blake, Grant C.
Abstract:: The Direct Reactor Auxiliary Cooling System (DRACS) is a passive safety system capable of removing decay heat directly from the reactor core. Its modularity makes it scalable for use in reactors with various power levels. Work has previously been completed to support inclusion of the DRACS in liquid metal reactors...
