Effect Of Liquid Viscosity On Performance Of Wire Mesh Entrainment Separators, Raymond Paul Vogel

Theses

The knitted wire mesh entrainment separator, commonly referred to as a demister*, is in common use to separate entrained liquid from vapor streams. However, little quantitative information is available concerning the effect of physical properties of the entrained liquid on allowable gas velocities.

Studies were made on two demister styles to determine the effect of liquid viscosity on demister performance, Liquid viscosities from 0.9 to 12 centipoise were investigated using water, glycerine-water mixtures and heavy no. 2 fuel oil as the test liquids. Air was used as the gas medium in all cases.

Regression analysis of the test data indicates …

A Study Of The Effects Of Quick Freezing On Saturated Fragments Of Rocks, John W. Scott, George R. Laughlin

Kentucky Transportation Center Research Report

Quick freezing of a fragment of rock which is fully saturated with water is, perhaps, the most rigorous of all tests for soundness, durability, or resistance to weathering. So-called soundness or quality tests employed currently, or heretofore, for evaluating concrete aggregates are usually less rigorous inasmuch as the state of saturation at the outset of freezing is not at a critical level. Hence, the number of freeze-thaw cycles endured by a rock specimen undergoing freezing and thawing in the presence of available water may merely reflect the duration of the exposure before the rock becomes vulnerable to damage -- i.e., …

A Laboratory Investigation Of The Properties Of Coal-Bitumen Paving Mixtures, Gary Grant Howard

Kentucky Transportation Center Research Report

The principal objective of this study was to investigate the feasibility of using coal, and to a lesser extent coal mine wastes, as aggregate in bituminous paving mixtures. These local aggregates were laboratory tested in bitumen-aggregate mixtures and, more particularly, in so-called cold-mixes. The bitumen-aggregate mixtures were evaluated by the Immersion-Compression Test, ASTM D 1075-60, with modifications for cold mixtures recommended in the Public Roads Journal (4).

In this initial study, since it was not possible to evaluate all types of mixtures, the primary question of whether coal and its waste products can be used as road aggregate could not …

Generalized Programs For Heat Transfer Analysis., Ceylung Chu

Masters Theses

"This report presents numerical methods for calculating temperature distributions in any physical system in which heat transfer is taking place. The syste.11 may be at either a steadystate condition or a transient condition. The temperature distribution may itself be or primary interest, or it may be used further to calculate the flow or heat or thermal stress.

The system under investigation is divided into a certain number of subdivisions, or so-called "regions". A reference point (node point) will be taken as representative for the region which includes that point. The temperature at the "node point11 is taken to be the …

Experimental Evaluation Of Thermal Stresses On The Outer Surface Of A Thick-Walled Tube., Vinodray T. Patel

Masters Theses

"In this investigation an attempt has been made to measure thermal stresses on the outer surface of a thick- walled tube. The inside surface was heated by steam passing through the tube while the outer surface was cooled by water. Two temperature compensated strain gages were used to measure strains in the tangential and axial directions respectively. The advantage of using this type of strain gage is to avoid the use of a dummy gage to compensate for the temperature effect.

The analytical solution to the problem was derived and the values of thermal stresses were calculated theoretically and compared …

A Rheological Investigation Of Asphaltic Materials, W. A. Mossbarger Jr.

Kentucky Transportation Center Research Report

Asphalts, serving as cements or binders in bituminous pavements, behave essentially as purely viscous, mobile, liquids at high temperatures and assume varying degrees of viscoelasticity, plasticity, elasticity, etc., upon cooling. They stiffen to a semi-solid state at cold temperature and do not. exhibit a discrete melting or freezing point, Saal (1)* classifies bitumens into three types according to their rheological properties at normal temperatures. They are: 1) those which behave entirely or almost entirely like Newtonian liquids, 2) those which show elastic effects during initial deformation and which exhibit Newtonian flow thereafter, and 3) those which show almost complete resilience …

Attack The Rabbit At Home : Destroy Warrens And Harbourage, J S. Crawford

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

Effective rabbit destruction often calls for a carefully worked out control programme consisting of poisoning, fumigating and warren and harbourage destruction.

Possibly the most effective means of not only controlling rabbits but ultimately eradicating them from holdings is the destruction of warrens and harbourage.

Opposed Disc Plough Furrows Hard Kimberley Soils, Department Of Agriculture, Western Australia

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

THE work of reclaiming the eroded areas of the Ord River catchment has posed special problems for field staff of the Department of Agriculture engaged on this large scale project.

Thousands of miles of furrows must be contour-ploughed and seeded in extremely hard ground over big areas of eroded country.

Migratory Movements Of Emus And Control Efforts, John L. Long, T. J. Tozer

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

ALTHOUGH little data has been recorded on movements or migrations of the Emu (Dromaius novea-hollandiae), it is well known throughout the farming community that some such movement occurs in September and October in most years at least.

Zirconium Chloride Nuclear Battery, Lonnie J. Shalton

Masters Theses

"An investigation of the neutron absorption characteristics of zirconium chloride was made to verify the reports of Chicago Development Corporation (5810 47th Ave., Riverdale, Md.) that ZrCl Blight be used as a power source for a nuclear battery. The company detected what they believed to be a beta current when the ZrCl was bombarded with neutrons from a slightly enriched uranium source. Investigation using higher powered neutron sources revealed that such a current was highly improbable and the company incorrectly interpeted the phenomena. Reports in the literature also confirmed that an electric current from the ZrCl using a low powered …

A Study Of The Eddy Diffusivity In Turbulent Heat Transfer, Frank Fu-Kun Tao

Doctoral Dissertations

"The purpose of this investigation was to determine the eddy thermal diffusivity values as a function of radial position at various Reynolds numbers for a fluid flowing turbulently in a pipe. The ratios of the eddy thermal diffusivity and the eddy viscosity were also investigated.

A vertical column of copper tube two inches in diameter was constructed which consisted of an entrance section for the development of the velocity profile and a heating section for the development of the temperature distribution. The heating section was jacketed and maintained at a constant wall temperature at about 103 ° F by the …

A Study Of Plane And Spherical Compressional Waves In A Voigt Viscoelastic Medium, Gerald B. Rupert

Doctoral Dissertations

"In investigating the behavior of waves traveling through cohesive solids, two assumptions are usually made: that the propagating medium is either elastic or viscoelastic, and that the wave is either planar or spherical in form. For small distances from the source of the disturbance the medium can be considered elastic and the wave spherical rather than planar. The assumption of elasticity allows considerable simplification of the mathematical analysis, and assuming a spherical wave form is an acceptable approximation if the initial disturbance is essentially a point source and the propagating medium is nearly homogeneous. However, for large distances from the …

A Determination Of The Theoretical Stresses In A Deep Beam., James William Tritz

Masters Theses

"This paper presents an analytical solution of the stress distribution in a deep beam of finite length. The beam being considered is analyzed as one of plane stress. The method employed superimposes two stress functions each of which is a trigonometric series. The first stress function satisfies all boundary conditions except that of zero stress on the vertical faces. The second function is found, so that, when combined with the first function, all boundary conditions are satisfied. The IBM 1620 digital computer is then used to find the stresses for a particular beam. The results of this analysis are then …
