Thermal Expansion Of Pb3o4, Charles A. Sorrell

Materials Science and Engineering Faculty Research & Creative Works

Thermal expansion of Pb₃O₄ was investigated by high‐temperature X‐ray diffraction. The coefficient in the a0 direction is 14.6x10−6/°C. Expansion in the c0 direction is 32% greater, with a coefficient of 19.3x10−6/°C. Coefficients of expansion are linear from 25° to 490°C and are comparable with those of tetragonal and orthorhombic PbO. Copyright © 1971, Wiley Blackwell. All rights reserved

Structure And Properties Of Silver Borate Glasses, E. N. Boulos, N. J. Kreidl

Materials Science and Engineering Faculty Research & Creative Works

Clear glasses form in the system Ag₂O‐B₂O₃ up to about 35 mol% (65 wt%) Ag2O. Infrared absorption, thermal expansion, and density data indicated an analogy to the Na₂O‐B₂O₃ system. Pentaborate‐triborate group pairs appear to be formed on addition of Ag₂O to B₂O3 up to 20 mol% Ag2O and diborate groups from 20 to 33 mol% Ag₂O. This interpretation is supported by the comparison of the infrared absorption spectra of quenched and crystallized glasses. One crystallization product, Ag₂O‐4B₂O₃, was …

Clay Cover For Roaded Catchments, J L. Frith, R. A. Nulsen

Journal of the Department of Agriculture, Western Australia, Series 4

RECENT dry years have stimulated interest in improved catchments for farm dams. Although roaded catchments have been installed on many farm dams in Western Australia, most of them fall short of their potential for increasing run-off.

Cylindrical Couette Flow Experiments In The Transition Regime, Darryl J. Alofs, George S. Springer

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Density Distributions Were Measured in Rarefied Argon Contained between Two Concentric Cylinders, the Inner One Rotating, the Outer One Stationary. the Experiments Were Performed with a Mach Number Near Unity, based on the Surface Speed and Surface Temperature of the Rotating Cylinder. Particular Attention Was Focused on Obtaining Data in the Slip and Transition Regimes Where the Knudsen Number, Defined as the Ratio of the Mean Free Path to the Gap Size between the Cylinders, Varied from 0.04 to 1.07. the Density Distributions Were Measured by Observing the Gas Luminescence Induced by the Passage of a Narrow Beam of High …

An Approximate Model For The Static Operation Of A Fluidic Amplifier Employing Axisymmetric Jets, Richard T. Johnson

Mechanical and Aerospace Engineering Faculty Research & Creative Works

An approximate mathematical model for the static, no-load (blocked receiver) operation of a fluidic amplifier employing axisymmetric jets is developed. The amplifier is similar in concept to the three-terminal modulator developed by the Johnson Service Co. The approach used in developing the model assumes that the complex flow phenomena can be represented by the combination of several elementary flow problems. The model employs the concept of an equivalent power nozzle in describing downstream flow with a control signal present. Experimental results are presented to justify assumptions and evaluate parameters. © 1971 by ASME.

Identification Of Centers Of Influence For Urban Areas, Robert W. Meyer

Doctoral Dissertations

"A method is developed for the identification of the spatial locations about which urban population densities tend to be distributed. The identification of these "influence centers" is based upon the use of available census data. The method is developed for application to any population characteristic which can be logically represented in terms of spatial density. Examples of such characteristics are; total population, population by race, and population by income group. The method is empirically developed and verified for restricted spatial distributions using artifically generated census tract information. These spatial distributions are compatiable with population distributions that are most readily modeled …

Ladder Network Transfer Function Characteristics, Thomtavanit Hatayodom

Masters Theses

"This thesis investigates the network characteristics and synthesis procedure previously developed. As a result of this investigation, location of the absolute minimum values of Navot's method is determined; a procedure is given for obtaining more desirable component values for a given ladder network without changing its transfer function; a procedure is given for obtaining the source location in a ladder network that yields the desired numerator degree of its transfer function; and a computer program for helping to obtain the above result is presented"--Abstract, page ii.

A Study Of A Nitrogen Heat Pipe, Jay Dudheker

Masters Theses

"An experimental heat pipe, 33.25 inches long and 0.75 inches in diameter, with modacrylic fiber wick and liquid nitrogen as its working fluid was constructed to study the operating characteristics of a cryogenic heat pipe. The effective thermal conductivity and the axial temperature distribution were determined for various levels of power input. The effect of inclination angle on the above parameters was also measured"--Abstract, page ii.

Design Of A Semi-Automatic Transmission, Yogendra Prahladray Buch

Masters Theses

"Design of a semi-automatic four-speed transmission for automotive engines with moderate horsepower is described. The basic configuration consists of main and countershafts and five pairs of constant-mesh gears. Engine torque is transmitted through an input gear pair to the countershaft, and finally to the output shaft through a selected output gear pair. Selection is accomplished by engaging one of five hydraulically operated clutches located on the countershaft. Engagement fixes the desired gear to the countershaft and engine torque is then transmitted to the mating gear, which is fixed to the output shaft. Fourth speed is obtained by coupling the input …

The Effect Of Diameter On The Film Boiling Behavior Of Liquid Nitrogen, William Joseph Wafer

Masters Theses

"A film boiling heat transfer study was conducted for liquid nitrogen at atmospheric pressure. The heat transfer surfaces used were cylinders with outside diameters of 0.450, 0.650, 0.850, and 1.000 inches. The temperature differences covered were from approximately 150ºF to approximately 600ºF. The data indicate that the heat flux will decrease to a minimum then increase slightly as the diameter of the heat transfer element is increased at constant temperature difference. The heat transfer coefficient is expected to approach a flat plate correlation as the diameter approaches infinity"--Abstract, page ii.

Free Vibrations Of Circular Cylindrical Shells, Sushil Kumar Sharma

Masters Theses

"In this report bending theory of shells is used to determine the natural frequencies and mode shapes of circular cylindrical shells. The governing eighth-order system of differential equations has been put in a form which is especially suitable for numerical integration and application of different sets of homogeneous boundary conditions. The Holzer method is used to solve the eigenvalue problem. During numerical integration of the differential equations, the exponentially growing solutions are suppressed whenever they become larger than previously selected values. Numerical results are obtained for various shell geometry parameters and for three different sets of homogeneous boundary conditions. These …

A Triangular Element For Numerical Solutions Of Axisymmetric Conduction Problems In Cylindrical Coordinates, Prafulla Chandra Mahata

Masters Theses

"The triangular element is one of the many suitable elements which are used in finite difference methods as applied to conduction heat transfer. Such elements find many applications in conduction problems in Cartesian coordinates. This work proposes a new triangular element for axisymmetric conduction problems in cylindrical coordinates. The validity and workability of the networks formed by the proposed triangular elements are strengthened by selected examples. The work is completed by the application of the triangular element to an industrial problem having irregular boundaries. The results are compared with the solution obtained by the finite element method"--Abstract, page ii.
