Simultaneous Development Of Velocity And Temperature Profiles In The Annulus With Laminar Flow And Both Walls At Constant Temperatures, Stephen Lothair Ritchie

Theses and Dissertations

Forced convection heat transfer in the entrance region of tubes and ducts has been studied extensively since the pioneering work of Graetz. Most of the published solutions for axial flow heat transfer are based on the idealization of either fully established or uniform velocity profiles with developing temperature.

Analysis And Discussion Of The Effect Of Heat Loss From The "Insulated" Face Of Thin Foil Heat Flux Meters, Mont Johnson Stevens

Theses and Dissertations

The object of this work was to investigate the effect that heat losses from the "insulated" face of thin foil heat flux meters has upon the sensitivity of heat flux meters. In the past it has been characteristic of any analysis done on heat flux meters to assume that the insulation on the back face of the foil was a perfect insulator and thereby neglect the effects of heat losses from this "insulated" face. It is hoped that the information given in this thesis will be of value in determining how the geometric and heat transfer parameters affect the operation …

Investigation Of Aerodynamic Hysteresis, Gerald Heber Peterson

Theses and Dissertations

The word hysteresis is derived from a Greek word meaning "to lag 'behind". As specifically applied to fluid flow around bodies with transient angles of attack in and near the stall region, "aerodynamic hysteresis" is used to describe the effect of delay in boundary layer separation and reattachment upon the lift, drag and pitching moment. Experimental work done on airfoils by H. Studer showed that for increasing angles of attack flow "separation is delayed to an angle of attack appreciably greater than that for a stationary airfoil. On the return movement, re-establishment of a smooth flow is also delayed." [1]* …

Design Of Regeneratively Cooled, High Temperature, Clean Gas Plasma, Roger Carver Bartlett

Theses and Dissertations

The objective of this thesis was the design of a regeneratively cooled, high temperature, clean gas plasma generator facility. This facility was desired to extend the high temperature research capabilities of the Department of Mechanical Engineering.

Trends In Promotion And Advertising Techniques Of Household Electrical Appliances By The Electric Utility Industry, Morris H. Toppila

Theses and Dissertations

The purpose of the study was to trace the development of national co-operative appliance advertising and promotional activities of the electric utility industry from 1882 to 1963. The principle source of information was the electrical trade magazines.

The advertising program of the electric utility industry has changed from emphasis on direct selling to coordination of national co-operative appliance campaigns. Advertising co-operation between retailers, manufacturers and the electric utility industry has been in existence since 1933.

The "Live Better Electrically" campaign is the most recent and successful of any co-operative promotional and advertising program. The Edison Electric Institute, representing the electric …

Evaluation Of Methods Used In The Determination Of Stability Constants Of The Thallium (Iii)-Chloride System At Twenty-Five Degrees, Nelson Kent Dalley

Theses and Dissertations

The difficulties encountered in the determination of equilibrium constants in systems with small, not directly rneasureable free ligand concentrations are discussed. These difficulties are illustrated using the determination of the formation constants of the Tl(III)-Cl- system as a specific example. Four methods are used and evaluated in this study. They are (1) the corresponding solutions method, (2) the method of Fronaeus, (3) the solubility of AgCl in Tl(III) solution method and (4) the method of Hugus. A discussion and derivation of each of these methods is given. The first three methods given and free ligand concentration data from which formation …

The Fluidized Drying Of Lignite, Chi-Hwi Wang

Theses and Dissertations

A continuous fluidisovi bed drier was designed and constructed for drying of lump lignite. The fluidised Led was 2 ft. long, 0.5 ft. wide and 1 ft. deep. The support was a grid of 1/2 in. steel rods with 1/4 in. clearance between them. Hot coiubustion gases war© used to fluidize and. dry the lignite, and a superficial gas velocity of 30 ft./sec. was used, Lamp lignite of the size range 3/4 in. x 1/4 in. and 354 moisture was successfully dried in the equipment. The range of successful operation was 400 to 600 °F inlet gas temperature and 400 …

An Experimental Investigation Of The Effect Of A Constant Body Force Field Upon The Drag Coefficient Of A Sphere, Brent Evans Boyack

Theses and Dissertations

The object of this thesis was to present the method and results of an experimental determination and correlation of the drag coefficients of accelerating spheres.

Teaching Transcription On The Secondary Level: Theories And Practices, Robert Gryder

Theses and Dissertations

The purpose of this study is to describe and explain the social disorganization and community upheaval of Native Americans in Elbowoods created by the construction of the Garrison Dam. The construction of the Garrison Dam in 1954, by the United States Army Corps of Engineers, was devastating not only for Fort Berthold Indian Reservation but also for Elbowoods. Flooding of the thousands of acres caused the residences of Elbowoods to give up farmland, natural shelter for human and cattle, family structure, community gardens, and a way of life that existed for thousands of years.

The data was collected by interviews, …
