Fully developed laminar natural convection in a vertical parallel plate channel with symmetric uniform wall temperature

Creator:: Willie, Robert H.
Abstract:: Described in this thesis is an investigation of the fully developed natural convection heat transfer in a vertical channel formed by two infinitely wide parallel plates maintained at a uniform wall temperature. Closed-form solutions for the velocity and temperature profiles are developed along with local and averaged Nusselt numbers. The...

Heat transfer during the piston-cylinder expansion of a gas

Creator:: Rodrigues, Matthew Jose
Abstract:: The expansion of a gas within a piston-cylinder arrangement is studied in order to obtain a better understanding of the heat transfer which occurs during this process. While the situation of heat transfer during the expansion of a gas has received considerable attention, the process is still not very well...

Effects of orifice geometry and surface boundary condition on heat transfer of impinging jet array

Creator:: Kanokjaruvijit, Koonlaya.
Abstract:: The effects of the orifice geometry and the surface boundary condition on the heat transfer distribution to a flat surface of an impinging jet array were investigated. The jet array impinged normally onto the surface which was either isothermal or had a uniform heat flux. The experiments were performed for...

Experimental investigation of supercritical heat transfer of carbon dioxide in parallel square microchannels with a single-wall constant heat flux boundary condition

Creator:: Zada, Kyle R.
Abstract:: In the vicinity of the pseudocritical point, supercritical carbon dioxide (sCO₂) undergoes a steep change in properties from “liquid-like” to “gas-like” as it is heated at a constant pressure. At the same time, there is a large spike in specific heat which can yield high heat transfer coefficients and heat...

Fully developed laminar natural convection in a vertical parallel-plate duct with constant wall heat flux

Creator:: Aktan, Gülçin
Abstract:: The problem of heat transfer due to free convection in a channel formed by two parallel, isoflux, vertical plates is of considerable importance in electronic cooling applications, thermosiphons, the optimum spacing of plates or components, industrial stacks, heat exchangers, nuclear power plants and combustion involving vertical walls. Although in each...

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...

Lateral fluid motion in nucleate boiling through asymmetric surface structures

Creator:: Kapsenberg, Florian
Abstract:: This thesis presents a feasibility study of a means to passively effect liquid motion parallel to a heated surface though surface geometrical modifications. Such a passive system is beneficial for electronics cooling applications as it reduces the pumping equipment normally required in flow loops and is desired for space applications,...

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...

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...
