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...

A pipe entry length solution for heat transfer and flow in Powell-Eyring fluids with temperature-dependent viscosity and constant flux boundary condition

Creator:: Etchart, David Ygnacio
Resource Type:: Masters Thesis

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...

Resource Type:: Masters Thesis

An evaluation of finite difference methods for calculating heat transfer in fuel pins with eccentrically placed pellets

Creator:: McNair, Gary W.
Abstract:: In fuel pin fabrication, there is no assurance that a fuel pellet will be loaded concentrically. Therefore, azimuthal variations exist in the temperature field giving rise to asymmetry in the neutron flux distribution and pin stresses. Calculations must be made to determine the two dimensional temperature profile which may then...

An experimental investigation of heat transfer in the transition and turbulent regimes for natural convection in mercury in a uniformly heated vertical channel

Creator:: Humphreys, William Warren
Resource Type:: Masters Thesis

An experimental investigation of natural convection heat transfer from an array of uniformly heated vertical cylinders to mercury

Creator:: Dutton, Jonathan Craig
Abstract:: An experimental investigation was conducted for natural convection heat transfer in an array of uniformly heated vertical cylinders in mercury. The test section consisted of seven electrically heated cylinders of 1.365 inch diameter and 3.825 inch heated length arranged in an equilateral triangular pattern. In order to preclude side flow...

An experimental study of heat transfer in a large particle heated fluidized bed

Creator:: Gosmeyer, Clayton David
Resource Type:: Masters Thesis

An experimental study of natural convection in air between a vertical isothermal flat plate and a parallel insulted flat plate

Creator:: Lee, Soon Mo
Abstract:: The free convective heat transfer phenomena in air between two vertical plates 24 by 38 inches spaced 15.895 mm apart, was investigated in this experimental study. One plate was isothermal and, the other adiabatic. A quartz fiber anomometer was used for measuring local velocities in the air between the vertical...

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...
