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...

Flow characteristics of semi-confined impinging jet arrays

Creator:: Dano, Bertrand P. E.
Abstract:: The present study proposes to investigate the flow structure of different arrays of jets impinging on a flat surface enclosed by three walls, creating a channel that forces the air to leave in one preferential direction, generating a self sustain crossflow. Details of both the mean and some turbulence quantities...

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...

Heat generation rates of nonfissionable materials in a nuclear reactor environment

Creator:: Zimmerman, Paul James
Abstract:: Radiation induced heat generation rates of several nonfissionable materials were measured calorimetrically in a nuclear reactor environment. The calorimeter was uniquely designed to allow many materials of grossly different heat generation rates to be measured. heat transfer characteristics of the calorimeter were determined analytically and experimentally. Materials were chosen to...

An analytical model of heat transfer to a horizontal cylinder immersed in a gas fluidized bed

Creator:: Adams, Ronald Lynn
Abstract:: A steady gas convection model of heat transfer to a horizontal cylinder immersed in a gas fluidized bed is presented. Contributions due to flow within attached bubbles as well as the interstitial voids are included. The interstitial flow is approximated as flow within a series of double cusped channels and...

Analysis of heat transfer, including axial conduction, for laminar tube flow with arbitrary circumferential wall heat flux

Creator:: Faghri, Mohammad
Abstract:: This thesis is concerned with the analysis of heat transfer in a tube with forced flow under conditions of an arbitrary variation of wall heat flux both axially and circumferentially. This total study is separated into two distinct problems which are presented separately. The first is the case of a...

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...
