Investigations concerning heat transfer involving wedge-shaped configurations

Creator:

King, John Michael

Abstract:

The temperature field inside a "truncated" wedge is investigated. For this purpose the two dimensional Green's function of the heat equation for this domain is established. Further applications of these results center around a problem of heat conduction investigated by Lebedev.

Masters Thesis
An analytical model of radiative and convective heat transfer in small and large particle gas fluidized beds

Creator:

Fatani, Abdulhadi Ahmed

Abstract:

A complete analytical model of radiative and convective heat transfer to a horizontal tube in small and large particle gas fluidized beds has been developed. In the model the bed of particles consists of an emulsion phase and a bubble phase. The emulsion phase is approximated by a series of...

Dissertation
Heat transfer between moving beds of solids and a vertical tube

Creator:

Obuskovic, Nevenka S.

Abstract:

Heat transfer to moving packed beds of solids has been studied extensively but predictions are usually specific to the experimenter's own equipment. In order to obtain a more general predictive equation, the heat transfer coefficient was measured for a single vertical tube immersed in a moving packed bed of glass...

Dissertation
Modeling in-situ vapor extraction during flow boiling in microscale channel

Creator:

Salakij, Saran

Abstract:

In-situ vapor extraction is performed by applying a pressure differential across a hydrophobic porous membrane that forms a wall of the channel as a means of reducing the local quality of flow boiling within the channel. As the local quality is reduced, the heat transfer capability can be improve while...

Dissertation
Modeling a heat regenerator-reactor with temperature dependent gas properties

Creator:

Kulkarni, Milind S.

Abstract:

This thesis examines the transient response of a packed bed heat regenerator when heated from an initial uniform bed temperature. Very large (1700 K) temperature differences were studied as well as the effect of simultaneous chemical reaction in the gas phase. First the effects of temperature on physical and transport...

Masters Thesis
Extending the discrete maximum principle for the IMC equations

Creator:

Talbot, Paul W.

Abstract:

The implicit Monte Carlo (IMC) method [16] for radiative transfer, developed in 1971, provides numerical solutions to the tightly-coupled, highly-nonlinear radiative heat transfer equations in many physical situations. Despite its popularity, there are instances of overheating in the solution for particular choices of time steps and spatial grid sizes. To...

Numerical analysis of liquid cooling by natural convection for heated protusions simulating vertical plate-mounted electronic components facing an opposing plate

Creator:

Park, Sung-kwan

Resource Type:

Dissertation
Experimental simulations of a rotating bubble membrane radiator for space nuclear power systems

Creator:

Al-Baroudi, Homan Mohammed-Zahid

Abstract:

A rotating, flat plate condensation experiment has been developed to investigate the heat of the Rotating Bubble Membrane Radiator (RBMR). The RBMR is a proposed heat rejection system for space applications which uses working fluid condensation on the inside surface of a rotating sphere to reject heat to space. The...

Dissertation
Radiation from an infinite plane to parallel rows of infinitely long tubes - hottel extended

Creator:

Qualey, Douglas L.

Abstract:

A two-dimensional model for predicting the rate of radiation heat transfer for the interior of an industrial furnace is described. The model is two-dimensional due to the assumptions of the heat source as an infinite radiating plane and the heat sink as rows of parallel tubes that are both infinite...

Masters Thesis
Laminar natural convection within long vertical uniformly heated parallel-plate channels and circular tubes

Creator:

Vorayos, Nat

Abstract:

The problem of simple mathematical models of laminar natural convective flow within a long vertical parallel-plate channels and circular tubes kept at uniformly heated walls is revisited to seek a clear physical understanding of heat transfer mechanisms. A series solution method to analyze the fully developed flow and an integral...
