Analysis of energy conversion systems, including material and global warming aspects

Creator:: Zhang, Mingyuan
Abstract:: With the rapid increase of the world energy demand and consumption, the method and techniques to analyze, improve and optimize energy conversion systems have to deal not only with direct fuel exergy (energy) consumption, but also with other resources, which have associated exergy consumptions, and with environmental impacts, such as...

Functional analysis to inform early design decisions for novel systems with substantial operations and maintenance costs

Creator:: Algarra, Nathan
Abstract:: Long field-life systems are those for which operational, as opposed to capital, expenditures dominate the life time cost of the system. In established product categories, operational experience and historical maintenance data allows engineers to make informed decisions influencing maintenance during the early design stages when design changes are at their...

The wave energy resource of the US Pacific Northwest

Creator:: Lenee-Bluhm, Pukha
Abstract:: The substantial wave energy resource of the US Pacific Northwest (i.e. off the coasts of Washington, Oregon and N. California) is assessed and characterized. Archived spectral records from ten wave measurement buoys, operated and maintained by the National Data Buoy Center and the Coastal Data Information Program, form the basis...

Modeling Implantable Passive Mechanisms for Modifying the Transmission of Forces and Movements between Muscle and Tendons

Creator:: Homayouni, Taymaz
Abstract:: This thesis explores the development of biomechanical models for evaluating a new class of passive mechanical implants for orthopedic surgery. The proposed implants take the form of passive engineered mechanisms and will be used to improve the functional attachment of muscles to tendons and bone by modifying the transmission of...

Investigation of In-tube Non-equilibrium Condensation of Low Global Warming Potential Refrigerants

Creator:: Jacob, Tabeel A.
Abstract:: This work investigates the in-tube condensation of low global warming potential (GWP) zeotropic refrigerant mixtures R448A, R450A, R452A, R454B and R454C. These refrigerants have been proposed for a wide range of commercial heating, ventilation, air-conditioning applications, but their heat and momentum transport phenomenon were not well understood. Thus, in this...

An experimental study of natural convection in air between a vertical isothermal flat plate and a parallel insulted flat plate

Creator:: Lee, Soon Mo
Abstract:: The free convective heat transfer phenomena in air between two vertical plates 24 by 38 inches spaced 15.895 mm apart, was investigated in this experimental study. One plate was isothermal and, the other adiabatic. A quartz fiber anomometer was used for measuring local velocities in the air between the vertical...

A study of forces on simulated heat exchange tubes immersed in a cold fluidized bed

Creator:: Donovan, Jerry Eugene
Abstract:: The object of this research, project was to study how different parameters effect the magnitude and frequency composition of forces exerted on simulated heat exchange tubes immersed in a cold fluidized bed. Two arrays of tubes were assembled with the tubes mounted in an equilateral triangular pitch pattern. The center...

Characterization of Two Novel Machining Processes for Difficult to Machine Materials

Creator:: Doran, Michael P.
Abstract:: New materials with superior mechanical properties, such as increased strength and hardness, have been developed to allow for new and improved products. However, the mechanical properties that make these materials useful also makes them difficult to process using conventional methods. New machining processes need to be developed to generate products...

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...
