Decomposition Of Cr(Oh)₃ To Form Active Cr₂C₃, Timothy A. Clancy

Doctoral Dissertations

"This study was concerned with the sinterability of Cr₂C₃ powders produced by the calcination of a Cr(OH)₃ gel. The decomposition of the gel was investigated by thermogravimetric analysis, X-ray analysis and microscopic examination. Comparison was made between the size of crystallites as determined by X-ray line broadening and the size of aggregated particles as determined by independent means. These lineal measurements were compared to surface area measurements on the calcined powders. The degree of sinterability was judged from the density measurements on Cr₂C₃ pellets fired under air, oxygen and nitrogen atmospheres. Energies of activation of 25 and 20 kilocalories per …

Heat Transfer Between A Turbulent Round Jet And A Segmented Flat Plate Perpendicular To It, John Edward Chamberlain

Theses

Heat transfer between a room temperature, turbulent round jet and a segmented flat plate perpendicular to it has been investigated.

The heat transfer surface consisted of invar rings insulated from each other with silicone rubber. The source of heat was steam at atmospheric pressure condensing on the back of the heat transfer surface.

Since data were taken over a wide range of vertical distances between the nozzle and the flat surface both the potential cone and the fully developed regions of the jet were observed interacting with the heated plate.

It was determined that two modes of heat transfer occur; …

Water Quality Study Of Lake Mead, Dale A. Hoffman, Paul R. Tramutt, Frank C. Heller, Bureau Of Reclamation

Publications (WR)

This report presents Lake Mead Water quality data obtained from 1964 to 1966. The effect of filling Lake Powell on the water quality of Lake Mead is evaluated. General limnological principles and the present limnology of Lake Mead are discussed. Lake Mead has a warm monomictic annual temperature cycle characterized by summer stratification, fall overturn leading into a continuous circulation throughout the winter; temperatures never fall below 39 deg F (4 deg C). During stratification, lower dissolved oxygen values were recorded in the thermocline than in the epilimnion and hypolimnion. Mineral content increases from the upper to the lower end …

A Study Of A Differential Equation Found In Wave Propagation And Scattering Theory, Larry W. Thacker

Electrical and Computer Engineering ETDs

The study of a differential equation that is found in the study of the scattering of waves from an inhomogeneous media and in atomic collision theory is presented. Several integral formulations for obtaining approximations to the solution are discussed and studied. Means of determining the phase shift in electron scattering problems are presented, and two methods for obtaining the reflection and transmission coefficients are developed and discussed.

A Study Of The Operating Characteristics Of An Adiabatic Calorimeter, Carl L. Wheeler Jr.

Mechanical Engineering ETDs

1.1 General Problem

New technological developments in the areas of arc testing, hypersonic flow, rocket propulsion, and re-entry heat shield design require new thermophysical data on heat resistant materials. The present investigation is concerned with the development of a calorimeter which has the capabilities for obtaining specific and latent heat data on these materials in the temperature range of ambient to 1,000° C. The criteria for this development are

a. that operation be easy: the calorimeter should be operated by only one observer;

b. that data be rapidly determined: no more than two to eight hours should be required to …

Numerical Studies Of An Inverse Pinch Device, John Richard Freeman

Electrical and Computer Engineering ETDs

The inverse pinch configuration has been recognized as a possible means of producing stable, repeatable shock waves in a plasma for laboratory investigation. The simple geometry permits investigation of cases with or without an initial transverse magnetic field in an un-ionized or pre-ionized medium. Previous analytic work for this geometry has been restricted to a snowplow model, sometimes including coupling with the external circuitry. The solution presented here consists of a finite difference, Lagrangian coordinate system solution for a one-fluid hydromagnetic model. The hydromagnetic model chosen includes the effects of a variable degree of ionization, assuming a hydrogenic plasma. Complete …

The Overall Force-Deformation Relations Of Latticed Frames, Syamal C. Dasgupta

Civil Engineering ETDs

Most elastic bodies in the field of civil engineering are composed of discrete elements which are interconnected in some way. A distinct characteristic of such systems is the presence of jump discontinuity in the physical properties of the systems. Trusses, ribbed shells, multi­story frames, continuous and folded plates, built-in columns, etc. are a few examples of this kind. From the conventional methods of analysis of these systems, it can be realized that considerable effort is being expended to approximate the actual system by .means of a relatively simpler system. Most of the established methods of analysis of such systems involve …

(1) According to FM 21-205, 18 Jan 1944, "Field Manuals constitute the primary means of promulgating the basic doctrines of military training and operations."

(2) This manual supersedes FM 5-30, 1959.

(3) This manual is much different from the manual it superseded because before 1962 Engineer Intelligence was defined as intelligence about foreign military equipment and on military organizations analogous to the US Army Corps of Engineers. In addition, two civil organizations within the Corps of Engineers, the Board of engineers for Rivers and Harbors and the Beach Erosion Board, produced intelligence about foreign harbors and potential landing beaches of …
