Proportional integral derivative control of an oil-heated fractal-like branching microchannel desorber

Creator:: Davis, Keith R.
Abstract:: A PID controller was designed to control the performance of an oil-heated fractal-like branching microchannel desorber for use in an ammonia-absorption refrigeration system. Both the amount and concentration of ammonia refrigerant generated at the desorber can be controlled by choosing the rectified circulation ratio as the controlled variable in a...

The effect of small amounts of magnesium on the superplastic behavior of an aluminum-zinc alloy

Creator:: Abbott, Vaughn William
Abstract:: The base Al-Zn superplastic alloy was investigated at 250°C to determine the effect of small amounts of magnesium on mechanical properties. Six alloys of nominal composition 0.00, 0.10, 0.25, 0.50, 0.75, and 1.00 weight percent magnesium, constant 78 weight percent zinc, and variable 21 to 22 weight percent aluminum were...

Quantification of total and plastic 3D strain fields within micro-damaged polyurethane foam

Creator:: Sutton, Matthew T.
Abstract:: Local material damage that occurs within cellular solids, such as polymer foams and trabecular bone, and precedes local fractures of the cell struts or walls is called micro-damage. The accumulation of micro-damage within cellular solids is often undesirable, although it is thought to be vital to the development and health...

Wind tunnel simulation and field measurements of flow over a coastal headland

Creator:: Brownlow, Roger West
Abstract:: An experimental study was made of the average and turbulent wind characteristics of the flow over a model of a coastal headland. The scale of the model was 300:1, corresponding to a prototype size of 500 m. The data for validation of the model study was obtained from instruments mounted...

Thermal and seismic analysis of piping systems using classical methods

Creator:: Nisargand, Arun L.
Abstract:: "Piping Design and Engineering" first published in 1963 by Grinnell, Co. is widely used by engineers to perform approximate thermal stress analysis of high-temperature piping systems. The text consists of numerical constants to calculate end reactions and maximum bending stresses in a variety of piping configurations from known properties of...

Creep studies on Pheasant, Narcissus and Chukar aluminum conductors

Creator:: Patton, John Dennis
Abstract:: This thesis is an engineering report on the creep behavior of power transmission line conductors. Laboratory creep test results are reported for Pheasant, Narcissus and Chukar conductors. The report follows a standard nomenclature and format suggested by the International Study Committee No. 6 of Conference Internationale des Grands Reseaux Electriques...

Rational Fuel Design for Low Temperature Internal Combustion Engines

Creator:: Daly, Shane R.
Abstract:: This work introduces a new methodology to design transportation fuels offering improved efficiency and reduced emissions, aimed to complement both traditional and emerging engine technologies. Many of these emerging technologies are centered around exploiting low temperature combustion (LTC) strategies that offer improved efficiency and reduced emissions. However, a standardized fuel...

An experimental investigation of radiative and total heat transfer around a horizontal tube immersed in a high temperature gas-solid fluidized bed

Creator:: Alavizadeh, Seyed Nasser
Abstract:: This study is primarily concerned with the measurement of the local radiative component of total heat transfer around a horizontal tube immersed in a large particle fluidized bed at elevated temperatures.Total heat transfer was also measured in order to assess the relative radiation contribution.The radiation measurement probe employs a silicon...
