Analysis Of The Performance Of The Pressurized-Water Nuclear Reactor By Electrical Simulation - Analog Computer, Philip Bartells

Theses

This thesis demonstrates a method of analog simulation of a Pressurized-Water Reactor (PWR) using simplified techniques. The simulation is for the reactor vessel and is patterned after the "Yankee," the PWR owned and operated by the Yankee Atomic Electric Company of Rowe, Massachusetts, and built by the Westinghouse Corporation of Pittsburgh, Pennsylvania. The entire analysis is based on the one group model (postulated that neutrons in the reactor are of one energy). The areas analyzed are: 1. Reactor kinetics - one delay group 2. Temperature effects on reactivity A. Fuel temperature coefficient B. Moderator and coolant temperature coefficient. 3. Control …

Open-Loop Frequency Response Analysis Of A Jacketed Kettle With Internal Heating/Cooling Coil, Wayne P. Brenckle

Theses

This work was performed to investigate the response and stability of a jacketed kettle with internal heating/cooling coils and glasteel thermowell. This system was first analyzed mathematically by deriving transfer functions for each component and then combining all component equations together to give the overall system transfer function. The mathematical model was then checked by frequency response analysis of the system. Bode plots of the system were prepared and the effect of the thermowell was analyzed.

Nyquist plots of the system were used as the criteria for determining stability, and obtaining the open-loop gain necessary to give optimum closed-loop response. …

Heat And Mass Transfer In The Absence Of Air, James Joseph Howley

Theses

The effects of heat and mass transfer across a frosted heat exchanger operating in the absence of air was evaluated. It is felt that this work could be applied to processes such as desalination of water or the purification of materials by reverse sublimation.

The system consisted of a single 1/2” O.D. stainless steel tube mounted within a 3" O.D. plexiglas tube with the ends suitably flanged. A vacuum was maintained in the annular space. Refrigerated ethylene glycol passed through the inner tube in laminar flow. A series of runs with substantially air-free water vapor added to the annular space …

The Reaction Of Cyclic Acetals With N-Halo Compounds, Nicholas Hrinkevich

Theses

Chemical reactions were carried out to determine the products of the halogenation of cyclic acetals with N-halo compounds (specifically N-bromosuccinimide and N-chlorosuccinimide) under conditions essentially free of those directly associated with free radical mechanisms (photocatalysis, peroxides, azonitriles, etc.).

Cyclic acetals were prepared and halogenated with bromine (Br2) or N-bromosuccinimide (NBS) or N-chlorosuccinimide (NCS). The distilled product from each reaction after workup was analyzed by vapor phase chromatography (VPC). The major components from the VPC were collected and identified by either infrared (IR) or nuclear magnetic resonance (NMR) spectroscopy and elementary analysis.

A mixture of compounds was found in each distilled …

A Computer Program For Multicomponent Distillation From Start Up To Steady State, Leo Julian

Theses

A computer program is presented which develops for a multicomponent distillation column a composition and temperature profile as a function of time from initial start-up to steady-state conditions.

The program is written in Kingston Fortran II language for use on an IBM 1620 II machine. It is a Thiele-Geddes type solution, i.e. the total number of plates, feed plate, overhead and bottoms split are specified and the solution gives plate. compositions and temperatures. The material balance at any time is based on the composition at the previous time, increased (or decreased) by the net quantity added and removed as a …

Approximation Of Reaction Rate Models, Hsu-Tung Lee

Theses

In reaction rate studies, experimental data is interpreted and correlated in terms of various mathematical models. The converse of the modeling of practical problems is the task- of experimental determination of reaction mechanisms. Generally, this approach is classified into integral and differential methods. Both involve trial and error techniques. The mathematical model which satisfies the test becomes the equation for mechanistic representation.

Both the integral and differential methods have been tried. Generally speaking, the differential method is more advantageous than the integral. For one thing, the parameters which are involved in the nodal can be determined directly by the differential …

An Investigation Of Some Properties Of Liquids Near Their Freezing Points, Martin Irwin Pulver

Theses

Five normal alcohols were prepared to greater than 99% purity. Simultaneous viscosity and density measurements were made beginning at 20°C above the reported normal freezing point and ending at incipient crystallization.

It was assumed that viscosity could be expressed as a function of specific volume and absolute volume, and that a simple logarithmic function would give a suitable correlation. The resulting equation yielded viscosities with an average error of less than 0.8% for the entire collection of data.

Deviations from a previously established linear function were observed in the density data from about 5°C above the reported normal freezing point …

The Measurement Of Dispersion Coefficients, John Harold Rosenberger

Theses

This work describes a method of determining axial dispersion coefficients in a packed bed chemical reactor. This is done by measurement of the fractional conversion of acetic anhydride to acetic acid, by first order reaction in dilute solution. The reaction is carried out at various flow rates in a four inch diameter reactor packed with one-half inch Raschig rings. analysis is by the aniline-rater method. Calculation of the dispersion coefficients is by trial using a digital computer. The results are presented graphically and compared to results obtained by other methods. The results of this study are found to correspond to …

Thermal Conductivity Of Mixtures, Paul Joseph Orosz

Theses

A concentric cylinder type cell was designed and constructed tp measure thermal conductivity of liquids. The materials of construction were stainless steel and teflon, so that a wide variety of liquids could be tested.

The systems studied were aqueous solutions of methyl alcohol, ethyl alcohol, n-propyl alcohol, isopropyl alcohol, and tertiary-butyl alcohol. Thermal conductivity was studied as a function of composition.

The data obtained were fitted to quadratic equations by least squares analysis. For each system, an equation of the following type was obtained:

k_L = A + Bx_A + Cx_A²

where k_L is thermal …

Reactions Of Cyanides With Borazines, Lawrence Meehan

Theses

B-trichloro-N-trimethylborazine in a dry tetrahydrofurane solution was reacted with potassium cyanide,, and sodium cyanide. On analysis of this reaction mixture, the precipitate was shown to contain both potassium chloride, and potassium cyanide when reacted with- the potassium cyanide, and sodium chloride and sodium chloride when reacted with sodium cyanide. On repeated runs of these reactions, it was shown that the precentages of the chloride to cyanide was approximately the same.

Case History Of A Test Pile Program For The Redevelopment Of Newark Airport, Patrick De Michele

Theses

A pile load test program was conducted at Newark Airport to determine the most economical piles to be utilized to support the structure in the Redevelopment of Newark Airport. The controlling criteria were the pre-determined design capacity of 50 to 100 tons for the piles and conformance to the Newark Building Code regarding the maximum allowable loads on the Airport's bearing strata and the allowable settlements for test loaded piles. Thirty-four piles, ten timber, four steel H-piles, four pre-stressed concrete, seven cobi shell and nine steel pipe piles, were driven to determine driving characteristics of the piles and the reaction …

Ball Milling Of Non-Newtonian Dispersions, Barry S. Miller

Theses

This investigation attempts to obtain a better understanding of flow behavior of a pigmented dispersion in a ball mill.

A power-law fluid model was used to approximate the rheological behavior of the milled fluid. To correlate power data on each of 276 milled dispersions, this model was used together with power number, Reynolds number, Froude number; and some geometrical variables.

Laboratory size stainless steel jars containing stainless steel balls from 1/8 to 3/4 inches in diameter were used to Mill a pigment/binder/solvent system at various speeds for different periods of time.

A correlation of power number as a function of …

The Frequency Response Analysis Of A Reboiler-Condenser Under Condensate Control, Douglas F. Ready

Theses

In this investigation, the dynamics of a reboiler-condenser pair, with the reboiler operating under condensate control, were analyzed both theoretically and experimentally, and the results of the two analyses compared.

The theoretical analysis was performed using the standard method of Laplace transform transfer function synthesis.

The experimental study consisted of a frequency response analysis of the system response to sinusoidal variations of the steam condensate rejection rate.

Two mathematical models were developed, one quite rigorous but extremely cumbersome, the other neglecting all but the most important factors for the sake of simplicity.

The experimental data (in the form of Bode …

Potassium T-Butoxide-Initiated Elimination On Substrate 1,1,2-Trimethoxyethane, James Waldron

Theses

1-bromo-2,2-dimethoxyethane (I) was prepared in 68% yield from the addition of bromine to a solution of vinyl acetate and methanol. A Williamson ether synthesis, using sodium methoxide in methanol and I, gave 1,1,2-trimethoxyethane (II) in 48% yield. The compound (II) was the desired substrate for elimination reactions because it contains poor leaving alkoxide groups.

Many different reactions were investigated to convert II into 1,2-dimethoxyethylene. Among these were pyrolysis, acid catalyzed eliminations, and base initiated elimination reactions.

Best results were obtained using a bomb reactor, compound II as substrate, and potassium t-butoxide as the base. From this reaction, tertiary-butyl methyl ether, …

The Use Of Ektacolor Paper As A Pre-Press Color Proof, Keith Erb, John Suter

Theses

To test the usefulness of Ektacolor Professional Paper as a pre-press color proofing method, one set of three predictor equations for each of the four primary printing inks was derived relating additive exposures on Ektacolor to colorimetric solid ink densities. These relationship would not yield to simultaneous solution.

Chromaticity coordinates of several sets of solid inks were matched on Ektacolor with an error of 2-10 MacAdam noticeability units. Probably because of the differences in surface characteristics of Ektacolor and newsprint, a visual match was not achieved.
