Dynamics Of Submerged Cylindrical Shells With Eccentric Stiffening, Kerry Kier-Ten Chu

Dissertations

A theoretical analysis is presented for treating the free vibrations of submerged, ring stiffened cylindrical shells with simply supported ends. The effects of the eccentric stiffeners are averaged over the thin-walled isotropic cylindrical shell. The energy method is utilized and the frequency equation is derived by Hamilton's Principle. All three degrees of freedom are considered. Numerical results are presented for frequencies and mode separation for several cases of interest. Comparisons with previous theoretical and experimental results indicate good agreement. The cylindrical wave approximation and the plane wave approximation for the field equation were investigated. Their applicability was evaluated and the …

The Continuous Non-Equilibrium Parametric Pump: A Theoretical And Experimental Study, John Lawrence Rak

Dissertations

A continuous parametric pump in which the feed and product streams flow steadily both in upflow and downflow (hot and cold temperatures, respectively) is examined theoretically and experimentally. The model system is Sodium Chloride-Water-Bio Rad AG11A8 Ion Retardation Resin, a physical system characterized by relatively slow interphase mass transfer rates. For short half-cycle times, where interphase equilibrium is not approached, separation of the salt from water is found to be enhanced by longer half-cycle times, smaller reservoir displacements, and longer adsorbant columns. In most cases, separation improves with increasing number of cycles. However, steadily degrading separation is found to exist …

Deposition Of Suspensions In Laminar Flow In The Entrance Region Of Channels With Diffusive, Electrostatic And Gravitational Effects, Thomas Anthony Korjack

Dissertations

This investigation entailed the consideration of the deposition of suspensions in laminar flow in the entrance region of a parallel-plate channel, and both converging and diverging channels, under the combined influences of diffusive, electrostatic and gravitational effects. The fluid phase was assumed to be incompressible, steady and laminar; the particle phase was assumed to be steady, laminar, dilute, and with negligible lift force.

The complete solution of the problem involved solving the boundary layer equations for the completely viscous fluid phase, and the particulate momentum, continuity and potential equations for the particle phase. Since the resulting equations are non-linear partial …

Paper Recycling : Recovery Of Secondary Fibers By Selective Wettability, Gary Keith Welshans

Dissertations

A separation process has been developed which recovers similar paper grades from a mixed stock by selective wettability. This process capitalizes on the various paper additives which are intended to resist water wetting and result in paper flotation. While water can be used to achieve many desirable paper separations, the detention times required are excessive, and therefore, limit any industrial application. Surface-active agents, in low concentrations, can be used advantageously by reducing the detention times for all paper while the structure of the surfactant can be used to selectively recover similar papers over a controlled time period. Detention times have …

The Countercurrent Multistage Desorption Of The Acetic Acid/Water Solution With An Inert Vapor, Michael John Danko

Theses

The desorption of a acetic acid and water solution with an inert gas was experimentally investigated using a perforated plate distillation column having 17 actual trays. An inert air stream flowing countercurrent was used to strip the water from the acetic acid and water solution.

The feed composition was 0.2509 mole fraction acetic acid. The experimental results showed the best obtainable separation to be 0.16118 and 0.3965 mole fraction acetic acid in the overhead condensate and bottoms respectively, at an average column operating temperature of 56.0 degrees centigrade. The concentration of acetic acid predicted by calculation is 0.003917 and 0.9860 …

Semicontinous Ph-Parametric Pump : Experimental Study, Hsien-Chih Lee

Theses

Voidage of SP Sephadex (C-50) ion exchanger at different aqueous buffer concentration and the pH have been estimated from draining the interstitial aqueous. Experimental results of the SP Sephadex (C-50) voidage at pH cycling zone are in quantitative agreement with previous test method, so the voidage estimated from draining the interstital aqueous can be used in pH-parametric pumping. The optional displacement volume in semicontinuous pH-parametric pump of different buffer concentration can be predicted from voidage. A semicontinuous pH-parametric pump for separating proteins has been experimentally investigated using the model system haemoglobin and albumin on a. SP Sephadex (C-50) ion exchanger. …

A Kinetic Study Of The Reactions Of Poly-L-Lysine With 1-Halo-2, 4-Dinitrobenzenes, Raymond K. Rakowitz

Theses

The kinetics of the reactions of poly-L-lysine with 1-Fluoro, 1-Chloro, 1-Bromo, and 1-Iodo-2,4-Dinitrobenzenes have been studied. The investigation was done at 25°C as a function of pH and concentration. In all cases the rate of reaction increased as pH increased. In the reactions of Chloro, Bromo, and Iododinitrobenzenes with Polylysine the reaction rate is the composite of two rates; one associated with the random coil and one associated with the helical conformation. For the reaction of Fluorodinitrobenzene with Polylysine the reaction rate is the composite of four rates; two associated with the random coil and two associated with the helical …

Management Of Manpower Planning In A Job Shop, John E. Yadlon

Theses

The object of any system of manpower planning is to provide a means to optimize manpower utilization. Within this base there is the normal requirement to provide effective utilization of equipment, materials and manpower. In a production type of environment, studies, statistics, research and supervisory manpower are readily available to best optimize manpower planning. In a job shop environment only fragments of these elements are available. Also, the available supervisory time for studies and implementation of research into statistics is usually very small. The net result is that manpower management in a job shop is all too often guessed at. …

The Introduction Of A Computerized Production Control System In A Small Manufacturing Company, Harry Leroy Zimmerly

Theses

The purpose of this thesis is to acquaint the reader with the intricacies of introducing a computerized production control system into a small manufacturing company. To do this a hypothetical company was described as it existed with a manual production control system. The information flow of the manual system was described in detail.

Potential computerized production control systems with a shop data collection system were then investigated. A computerized system would expedite information flow, allow rapid assembly tracking, take accurate data and reveal the actual cost (including labor cost) of an assembly. This was done first by examining technical publications. …

Possible Efficiency Improvements In Residential, Gas Fired Furnances, Philip Louis Rinaldi

Theses

This project examines the problem of how to improve energy utilization in a residential space heating environment. Techniques for lowering unit energy consumption are developed and the feasibility of their implementation is discussed.

The project development first establishes the magnitude of the energy wastage problem for the individual consumer and its impact on the national scale. It must be emphasized that these represent two, sometimes distinctly different justifications for reducing energy use in the home. What may be considered only a small personal waste of $50 to $100 per year may indeed--when viewed in aggregate--represent a significant burden on the …

The Slow Settling Of A Sphere In A Viscous Fluid In The Proximity Of A Corner, Joseph Kisutcza

Theses

Experimental settling velocities for three different sizes of Delrin spheres in Ucon lubricant were determined at 20.2 degrees Celsius in order to confirm the validity of a theoretically derived equation for the settling of a sphere in the proximity of a corner. The experiments were conducted in a wedge shaped column with a circular sector base, filled with the viscous fluid, where the angle of the wedge was varied for experimental purposes. The distance from the wedge apex to the particle was also changed for the different runs.

The experimental data gave a good approximation of the values evaluated by …
