An Investigation Of Optimum Journal Bearings., Kulin Purshotam Maskai

Masters Theses

"Not much has been done towards calculating the "Optimum Bearing" from the point of view of maximum load capacity or minimum friction. It has been found that there 1 is not much difference in the "Optimum Bearing" proportions, as calculated, considering either minimum friction or maximum load capacity

Journal bearings are commonly used and they play a very important role in reducing friction and wear. Engineers use past experience in choosing a bearing for the given conditions. A bearing design can be obtained if 'Optium Bearing' proportions are calculated as suggested by Kingsbury (1) in his article on 'Optium Conditions …

Masters Theses

"The purpose of this thesis is to conduct an analytical analysis of a char-forming ablation material. This is one phase of ablation heat transfer.

Fourier's general equation for one dimensional heat conduction is transformed to moving coordinates and is then solved using the applicable boundary conditions. Solutions of this equation are valid for initial studies in ablation heat transfer"--Abstract, page ii.

Thermocouple Shape Influence On Response In A Dynamic Compressible Fluid Atmosphere, Philip J. Steger

Masters Theses

"This investigation was performed to determine whether the geometrical shape of a thermocouple used to measure the temperature of a dynamic fluid atmosphere had any affect on its recovery factor and time response.

A converging nozzle was used to establish a dynamic fluid stream in which shaped silver solder junctions of copper-constantan thermocouples were tested. The velocity of the working fluid, air, was about 1000 ft/sec at the test point.

The investigation was successful, within experimental limits, in determining that the recovery factor of a bare thermocouple junction is not influenced by geometrical shape The results agreed substantially with available …

A Study Of Rotational Critical Speeds For A Multi-Mass, Multi-Span System, Pravinchandra M. Upadhyay

Masters Theses

"It is well known that the unbalanced inertia forces present in rotating shafts set up violent vibrations in a transverse direction at certain speeds known as critical speeds, whirling speeds or whipping speeds. Therefore one who deals with the design of rotating machine parts, such as turbine rotors, multi-cylinder engine crankshafts etc., must consider transverse vibrations of rotating parts.

Practical solutions for finding the critical speeds of simple rotating systems, such as a single disk on a shaft with a single span, were derived by many authors. But as the number of loads and spans increases the problem becomes complex …

The shafts considered in this thesis are simply supported and symmetrically loaded with five concentrated masses. These five masses are placed at increments of 10 inches on a 60 inch shaft. The variable to be examined is shaft diameter, which is varied from 0.2 inch to 1 inch by increments of 0.2 inch. The effect of shaft weight, which is a function of …

A Study Of The Angular Velocity In A Liquid Induced By A Vortex In An Emptying Container, James Paul Hartman

Masters Theses

"Previously a limited amount of investigation has been done to describe the rotational motion of fluid in a draining tank. To date tank design has been based on trial and error, since the physical mechanisms of actual draining have not been recognized. This investigation has been made to develop a technique for the measurement of the motion of the fluid during the draining process and to present the results of the observed surface velocity of the liquid as a function of depth of fluid and its distance from the center of the vortex core. Many previous investigators of vortex behavior …

Parameters In Ablation Heat Sheilds, Franklin Chang Liang Lin

Masters Theses

"The desired result of this paper is a method of determining temperature distribution and burn off rate in a semi-infinite rod or shield subjected to a large heat flux. The possible methods of determination were investigated, and it was felt that an analytical approach turned out to be the most feasible.

The analytical analysis employed involves the use of the Fourier's general equation for one dimensional heat flow. Transformations from stationary to moving coordinates reduces the problem from unsteady state to steady state boundary conditions. The resulting equations can be applicable to the extent for the heat flow problems involving …

A Parametric Study Of The Heat Transfer Characteristics Of A Moving Band Heat Exchanger, Larry Hyde Brim

Theses and Dissertations

In recent years much attention has been devoted to the development of efficient heat exchangers. The regenerative or moving matrix heat exchanger is one type which has been considered. Most regenerative heat exchangers use one of the conventional types of high area matrices mounted in a drum or disk in such a manner that it can be moved in a continuous cycle from a cold fluid stream to a hot fluid stream and back again. A rather different approach to the design of a regenerative heat exchanger which has been patented in this country is a set of flexible moving …

Stress Analysis Of An Infinite Cylinder With An Irregular Shaped Cavity Using Complex Variable Techniques, Gerald H. Lindsey

Theses and Dissertations

The advancement of modern technology has brought with It a demand upon the engineer for more thorough analysis techniques. This has been precipitated by the advent of missiles and space-craft that do not permit regular inspections to determine causes of failure, crack propagation, design weaknesses, etc. Thus, a more complete analytical work must be performed to facilitate a foreknowledge of reaction and performance of a particular design to its environment.

A Literature Review Covering The Effect Of Residual Stresses On Fatigue Strength Of Steel, Clarence A. Calder

Theses and Dissertations

Fatigue fracture usually is defined as the failure of a part at a stress below its breaking stress due to repetitive loading conditions. It is now a well known fact that a part, designed for a maximum stress well below the yield point of the material, may be very apt to fail under cyclic loading conditions over a period of time. The metal appears to "wear out" after a time just like humans do and fatigue failure occurs. Metal fatigue may be contrasted to animal fatigue in that l) its detection before the latter stages is normally difficult if not …
