Use Of Thermal Storage For Load Management In A Solar-Augmented Heat Pump System, James Thomas Schmitz

Mechanical Engineering ETDs

Electric utilities are today faced with the dilemma of satisfying increasing demands for electrical energy while their ability to build new power plants is being severely curtailed primarily due to environmental concerns. By redistributing the power demand of individual customers (and thus the utility) with respect to time, greater overall electricity consumption can be met without increasing the generating capacity of the utility. This redistribution can be accomplished using thermal energy storage at the customer’s location. For heating and cooling of buildings, thermal storage, combined with off-peak period operation of the mechanical system's major electricity consuming equipment, can lower peak …

The Compatibility Of Mild Carbon Steel And Water In A Heat Pipe Application, David D. Kenney

Mechanical Engineering ETDs

The phenomena that govern the performance and affect the lifetime of heat pipes are reviewed. The phenomena include the corrosion of metals by aqueous solutions, the diffusion of gases through metals, and the effects of hydrogen on metals. Heat pipes of 1015 C.D. carbon steel were fabricated and operated with a control group of 304 stainless steel heat pipes over the temperature range from 140° to 300° C. Results indicate that carbon steel/water heat pipes perform as well or better than 304 stainless steel/water heat pipes over the temperature range covered in this test.

Lee's Moment Method Applied To Binary Flow In Jet And Channel Devices Used For The Aerodynamic Separation Of Uranium Isotopes, Edward Eugene Holcomb

Mechanical Engineering ETDs

Lees' moment method is applied to the problem of compressible, binary flow of uranium hexafluoride gas through a parallel plate chan­nel. The time-dependent numerical problem is solved to yield the steady state solution. The results obtained are preliminary to the solution of the flow field for the curved nozzle and colliding jet devices used in the aerodynamic separation of uranium isotopes. Lees' concept of two-sidedness of the distribution function doubles the number of variables required to describe the system, and the resulting set of moment equations is not easily solved. The assumptions of isothermal, hydrodynamically fully developed flow are made …

A Survey Of Structural Identification Techniques, Doris Evelyn Miller

Mechanical Engineering ETDs

This work is a collection and survey of system identification methods in the open literature. The motivation for the work was to find suitable methods of system identification for use in structural diagnosis. Methods surveyed include those which identify the system in terms of modal parameters, and those which identify the system either nonparametrically or in terms of arbitrary parameters. Both deterministic and stochastic methods are reviewed. Particular emphasis is placed on determining damping coefficients, and on a formulation known as modal synthesis. It is concluded that stochastic methods are better suited to the problem of structural diagnosis, and that …

Rebirth Of The Downtown Industrial District--Key To Revitalization, Chester Smolski

Smolski Texts

"Residents were there by the hundreds to welcome home one of their noteworthy product of a previous era. 'Old 299' had just returned from the Panama Canal Zone to its final resting place in the New Paterson Museum, a fitting climax for the 2-6-0 'Mogul' type steam locomotive that was born here in 1906. And June 6, 1979 marked the gala return of one of the few remaining American-made locomotives that were so instrumental in the construction of the Panama Canal by this nation in the period from 1904 to 1914, after earlier unsuccessful attempts by the French."

Inplane And Out Of Plane Buckling Of Thick Rings Subjected To Hydrostatic Pressure, Thomas Michael Juliano

Dissertations

The problem of inplane and out of plane buckling of a thick circular ring subjected to a hydrostatic pressure is analyzed from first principals. The equations of equilibrium from nonlinear elasticity theory are used to describe two adjacent equilibrium positions, i.e., an initial and final state. The initial position problem is assumed to be governed by linear theory. The resulting incremental value equations obtained by subtracting the two equilibrium states, are also linear in nature. These problems are reduced to a one dimensional ring theory problem by the method of power series expansion of the displacements in the radial and …

Axisymmetric Air Jet Impinging On A Convex Hemispherical Plate, David C. Chan

Theses

Experimental investigation was conducted on an axisymmetric, submerged air jet impinging normally on a smooth convex hemisphere. Three nozzle diameters of 0.5" (12.7mm), 0.375" (9.525mm) and 0.25" (6.35mm) were used and tests were run at Reynolds number range of 14,700 to 84,000.

The results obtained in the free jet and deflection zones were found to confirm the works of previous investigators. As for the fully developed wall jet region, the following points are noted:

1. The maximum wall-velocity decay was found to possess a slightly higher rate than that of either the flat plate or the concave hemisphere.

2. The mean velocity …

A Three-Dimensional Kinematic Model Of The Human Knee, Wayne Ke-Wung Li

Theses

This thesis describes two kinematic models of human knee which may be used to study the motion of the knee and the forces in the ligaments of the knee. In one model, the ligaments are simulated by rigid links connected to links representing the articulating bones at the centroids of the areas of insertion of the ligaments. The condylar higher pair connections are simulated by equivalent linkages connected by resolutes. In an advanced model, the rigid ligament links are replaced by springs.

The IMP procedure, a powerful kinematic linkage analysis method, is employed to study the motion and forces in …
