Investigations Of Several Variables In The Dwight-Lloyd Mcwane Ironmaking Process, James Orlan Hood Jr.
Investigations Of Several Variables In The Dwight-Lloyd Mcwane Ironmaking Process, James Orlan Hood Jr.
Masters Theses
"The Dwight- Lloyd McWane Ironmaking Process (D-LM) is the first commercial process of its particular type and one of the few commercial processes involving prereduction of iron ore in existence today. This presentation reviews some promising ironmaking processes which involve iron ore prereduction, with special attention being given the D-LM process. Although the D-LM process is continuous from iron ore to high quality molten cast iron, the research and discussion herein is limited to principal variables involved in the production of high quality carbonized pellets in the prereduction phase of the operation. The variables of process temperature and pellet carbon …
The Semibullvalene Question: A Semi-Empirical Molecular Orbital And Bond Energy Approach, Shiow Yeh Lee
The Semibullvalene Question: A Semi-Empirical Molecular Orbital And Bond Energy Approach, Shiow Yeh Lee
Masters Theses
"Semi-empirical molecular orbital calculations of the Extended Ruckel and MIND0/1 type have been performed on semibullvalene and the supposed transition state for its degenerate [3,3] sigmatropic rearrangement. The results have been coupled with bond energy calculations to ascertain whether semibullvalene is homo-aromatic or is undergoing a rearrangement of exceedingly low activation energy. A preponderance of the resulting data suggests that semibullvalene is homo-aromatic"--Abstract, page ii.
Initial Operation And Calibration Of The Umr Supersonic Axisymmetric Wind Tunnel, James Riley Murphy
Initial Operation And Calibration Of The Umr Supersonic Axisymmetric Wind Tunnel, James Riley Murphy
Masters Theses
"Initial testing and a preliminary calibration were conducted in the UMR supersonic variable Mach number axisymmetric blowdown wind tunnel facility. During initial operations problems were encountered with control valve seat failure, control valve response and stability, and automatic operation. After having brittle fracture failures with seats made of nylon, Teflon and Telfon-copper composite, a copper seat was found to perform satisfactorily with minimal valve leakage. Control valve response and stability were greatly influenced by the setting of the needle valve located between the total pressure probe and the controller. The needle valve setting was observed to depend upon the stagnation …

Effect Of Inclination On Film Boiling, Shih-Chang Lin
Effect Of Inclination On Film Boiling, Shih-Chang Lin
Masters Theses
"The object of this investigation was to determine the effect of inclination on the heat transfer for film pool boiling. The test plate used as the heater was made of Inconel-600 and heated electrically. Liquid nitrogen at atmospheric pressure was used as the test fluid. The heater was oriented at various angles from the horizontal position with the heater surface facing both upward and downward and the heat transfer coefficient was determined for each angle over temperature differences ranging from 450ºF to 750ºF. As the heater angle was increased from 0º (horizontal) to 90º (vertical), the heat transfer coefficient increased …
Recovery Of Trace Organic Pollutants By Solvent Extraction And Freeze Concentration, William Chih-Wen Chang
Recovery Of Trace Organic Pollutants By Solvent Extraction And Freeze Concentration, William Chih-Wen Chang
Masters Theses
"The objective of this investigation was to evaluate the use of batch type solvent extraction and freeze concentration in recovering trace organic pollutants from water. The work was performed using a simplified water system containing known concentrations of phenol, and natural water systems collected from three sources (Meramec Spring, Gasconade River near Jerome, and Missouri River in Jefferson City) with different levels of pollution. The simplified water system was used to evaluate the effect of the number of extractions, solvent to sample ratio, extraction time, initial organic concentration, pH, and turbidity on solvent extraction; and the effect of volumetric concentration …
Optumr A Digital Computer Program To Cost Optimize A District Heat Piping Network To Remove Waste Heat From Nuclear Power Reactors, James Richard Hendricks
Optumr A Digital Computer Program To Cost Optimize A District Heat Piping Network To Remove Waste Heat From Nuclear Power Reactors, James Richard Hendricks
Masters Theses
"The thermal pollution problem of a nuclear reactor electrical generating facility can be eliminated if an economical, productive use for the waste heat can be found. The computer program presented here is designed to investigate the economic feasibility of utilizing this waste heat to heat buildings. The program optimizes a district heating network using the reactor's rejected heat and performs a comparative analysis with a selected conventional heat rejection system. The results indicate that the system is feasible only if the reactor can be sited relatively close (5 miles) to an urban center. Increasing national concern regarding thermal pollution and …
Efficiency And Loss Mechanism Of The Electro-Fluid Dynamic Momentum Transfer Process Applied To Propulsion Systems Using Atmospheric Air As The Working Fluid, Roger Coy Crites
Efficiency And Loss Mechanism Of The Electro-Fluid Dynamic Momentum Transfer Process Applied To Propulsion Systems Using Atmospheric Air As The Working Fluid, Roger Coy Crites
Masters Theses
"The general equations governing EFD (electrofluid dynamic) flow are established, simplified, and solved in closed form to provide a mathematical model of an ideal EFD propulsion system. This mathematical model, in conjunction with an analysis of ion-neutral and neutral-neutral molecular collision phenomena, indicates that the cause of inefficiency in the EFD propulsion system is the system entropy increase associated with the diffusion of ion momentum through the neutral fluid. This loss mechanism is shown to be analogous to resistive heating losses in a constant voltage linear electrical network and can be minimized by obtaining minimum ion mobility. It is shown …
Surface Energy Determinations In Plexiglas, Li-King Chen
Surface Energy Determinations In Plexiglas, Li-King Chen
Masters Theses
"Under irreversible conditions an effective surface energy of plexiglas for notched bars deformed in three-point bending was measured. The various equations proposed for evaluating surface energy are described and values of surface energy obtained using these equations are reported for a variety of sample dimensions. A comparison has been made between the results obtained. The effect of different notch shapes, sharp V, square U and round, on calculated values and fracture characteristics are noted. The Griffith theory is shown to be valid for large crack dimensions"--Abstract, page ii.
Probe Detection Of Microwave Perturbation In A Magnetoplasma, Show-Ran Peter Wang
Probe Detection Of Microwave Perturbation In A Magnetoplasma, Show-Ran Peter Wang
Masters Theses
"When a microwave signal with a frequency near the electron upper hybrid resonance is applied to a magnetoplasma, it will excite the plasma. The perturbation of plasma can be detected by using Langmuir probes. The particular plasma used in this experiment is an argon discharge type and the density is relatively low (n~10⁸ cm⁻³). The electron temperature is about 7000º K. Because a magnetic field is applied to the plasma, it is necessary to use the probe theory in a magnetic field to calculate the electron number density from the electron temperature. In order to determine the electron upper hybrid …
Heat Transfer Through A Spherical Gas Shell, Adel Nassif Saad
Heat Transfer Through A Spherical Gas Shell, Adel Nassif Saad
Masters Theses
"The radiative transfer through an absorbing-emitting gas shell contained within black concentric spheres at uniform but different temperatures was investigated. A close form exact solution and an approximate solution were derived for the case of isothermal gas layer. The two solutions appear to compare well specially at low diameter ratios, and both agree with the radiative equilibrium solution in the thin limit. An approximate method was developed for the radiative equilibrium, non-isothermal gas layer, of the above problem. The method is based on the assumption of a hyperbolic emissive power distribution through the gas shell. The jump boundary conditions were …
The Anodic Oxidation Of Oxalic Acid On Au, Jean Louis Lucien Desmartin
The Anodic Oxidation Of Oxalic Acid On Au, Jean Louis Lucien Desmartin
Masters Theses
"The anodic oxidation of oxalic acid on Au has been studied at 25ºC in aqueous media. The reaction rate was measured as a function of potential, oxalic acid concentration, pH, and temperature in H₂SO₄-K₂SO₄ solutions. A change in the Tafel slope in going from the lower to the higher Tafel region is explained by an alteration of the reaction mechanism due to electrical interactions between adsorbed species and the anode. Further details of an oxidation sequence involving resonant forms of oxalic acid are proposed"--Abstract, page 1.
A Digital Computer Program For Studying Elasto-Plastic Structural Behavior Due To Cyclic Loading, Rameshchandra Chandulal Hazariwala
A Digital Computer Program For Studying Elasto-Plastic Structural Behavior Due To Cyclic Loading, Rameshchandra Chandulal Hazariwala
Masters Theses
"A computer program has been developed to study the behavior of plane stress structures under cyclic loading. Such phenomena as thermal ratcheting, alternate plasticity, shake-down and the Bauschinger effect may be considered. The incremental theory of plasticity has been used. The program deals with realistic conditions such as nonlinear strain hardening, nonlinear temperature distribution and occurrence of both compressive and tensile plastic flow. The concept of an average material property has been used. Thermal ratcheting of a beam subjected to a constant bending moment and a temperature cycle has been studied in detail. The analysis shows analytically that the rate …
Evaluation Of The Carbon Adsorption Method With Parallel Solvent Extraction Studies, Stanley Kent Wagher
Evaluation Of The Carbon Adsorption Method With Parallel Solvent Extraction Studies, Stanley Kent Wagher
Masters Theses
"In spite of the importance of the carbon adsorption method (CAM) in determining drinking water quality and its wide use in research and plant control studies, little work has been undertaken to quantitatively and qualitatively evaluate the method, especially under field conditions. This investigation was, therefore, undertaken in order to develop a test system consisting of equipment and procedures which would make possible the field evaluation of the carbon adsorption method by parallel solvent extraction studies, and to employ this system in preliminary field investigations to establish guidelines for the experimental conditions required for its effective application. The test system …
The Failure Criteria And Deformational Moduli Of Granular Rock, Kyung Chul Ko
The Failure Criteria And Deformational Moduli Of Granular Rock, Kyung Chul Ko
Masters Theses
"Analytical solutions of stress for composite material are obtained by means of mathematical theory of elasticity, assuming spherical inclusions and uniform displacements of boundaries of representative elements. These solutions show that the failure criteria of composite materials are complicated functions of the elastic moduli of matrix, inclusion and composite, and the volume ratio of matrix and inclusion. Combining this theory with Griffith's theory gives a new criteria for brittle failure of granular rook. This theory appears to provide a nearly perfect model for granular rooks, inasmuch as: a) most assumptions used in other criteria are eliminated, b) most phenomena in …
