Numerical study of natural convection in square partitioned and non-partitioned enclosures

Creator:: Sukkaset, Prasart
Abstract:: Heat transfer characteristics and associated temperature and flow fields for natural convection in two-dimensional, square, partitioned and non-partitioned enclosures have been determined for Grashof numbers ranging from 10³ to 10⁶. The vertical side walls of the enclosure are isothermal with all other surfaces assumed to be adiabatic. An adiabatic partition...

Dislodgement and deformation of microbubbles in laminar channel flow

Creator:: Tence, David A.
Abstract:: In this thesis the critical parameters involved in the dislodgement and deformation of microbubbles in laminar channel flow, are determined and evaluated. Experimentally the effects of surface tension, viscosity, fluid flow rate, density, and bubble diameter on bubble dislodgement were evaluated. A theoretical scale analysis was performed which provided a...

Cold trap performance : a general analysis

Creator:: Rothwell, Micheal Olin
Abstract:: A cold trap is a device used to remove certain impurities from a liquid metal by controlled precipitation of such impurities. An investigation of the thermal characteristics of laminar flow in two air-cooled cold traps was made. This investigation showed that the sodium heat transfer rate is a function of...

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...

Performance of rotary regenerative heat exchanger--a numerical simulation

Creator:: Bae, Young Lib
Abstract:: This thesis examines the transient and steady-state temperature performance of a rotary regenerative heat exchanger. In contrast to previous studies on this problem, fluid flow in the circumferential direction was considered. Appropriate modeling was included to measure the effect of carry-over on the differential equations describing mass and energy conservation....

Solid/liquid phase change in small passageways : a numerical model

Creator:: Coven, Patrick J.
Abstract:: During the operation of phase-change ink-jet printers a bubble formation phenomenon often occurs. These bubbles are detrimental to the operation of the printer and substantial efforts are made to remove them. The objective of this research was 1: to develop a fundamental understanding of how bubble or void formation occurs...

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...
