A Preliminary Experimental Study Of The Turbulence Decay In The Wake Of A Hemisphere In Free-Surface Flow, Jiin-Jen Lee May 1966

A Preliminary Experimental Study Of The Turbulence Decay In The Wake Of A Hemisphere In Free-Surface Flow, Jiin-Jen Lee

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Flows observed in open channels are usually turbulent. The word "turbulent" describes a motion in which an irregular velocity fluctuation (mixing or eddying motion) is superimposed on the main stream motion. The essential characteristic of turbulent flow is that the turbulent fluctuations are random in nature.

If Reynold's rule of averaging is used, the Navier-Stokes equations for laminar flow may be transformed into the Reynold's equations, which hold true for turbulent mean motion. The solution of Reynold's equations will properly describe turbulent flow. Unfortunately, the number of unknowns exceeds the number of equations; therefore the use of mathematical method to …


Streaming Current And Streaming Potential Induced By Water Flow Through Porous Media, Mohamed M. I. Abaza May 1966

Streaming Current And Streaming Potential Induced By Water Flow Through Porous Media, Mohamed M. I. Abaza

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was conducted to investigate analytically and experimentally the relationship between the rate of flow of water through porous material and the streaming current and streaming potential induced by this flow. The effect of dissolved salts in the permeating solution and the size of the soil particles was also investigated.

Results and conclusions of this study are summarized as follows:

  1. A modified procedure using the appropriate delay to insure stead state conditions was used for the measurements of both streaming current and streaming potential.
  2. The flow-pressure relationship was the same irrespective of the counter electro-osmosis (resulting from the streaming …


Proposed Remedial Design For Unstable Highway Embankment Foundation: I-64-6(6) 117, Bath County, Gordon D. Scott, Robert C. Deen Apr 1966

Proposed Remedial Design For Unstable Highway Embankment Foundation: I-64-6(6) 117, Bath County, Gordon D. Scott, Robert C. Deen

Kentucky Transportation Center Research Report

Early in 1966, during the construction of a large embankment between Stations 1738+00 and 1745+00 on I 64 in Bath County (I 64-6(6)117, SP 6-404-5G1), a serious slide occurred involving large quantities of the embankment material. After a visit to the site and a review of the subsurface information available, it was assessed that the slide occurred as a result of a bearing-capacity failure of the foundation material.


Kentucky Rock Asphalt Bases And Hot-Mix Surfaces; Experimental Construction, Robert L. Florence Apr 1966

Kentucky Rock Asphalt Bases And Hot-Mix Surfaces; Experimental Construction, Robert L. Florence

Kentucky Transportation Center Research Report

The objectives of this study are disposed toward the development of Kentucky Rock Asphalt for use as a traffic-bound base and surface on rural roads near its source and toward re-development of the material for use as hot-mixed, hot-laid, skid-resistant surface course for higher echelon roads. The material is a natural asphaltic-sandstone which occurs in considerable abundance in Edmonson County and in other outcrops of Pottsville sandstones bordering the eastern rim of the Western Kentucky Coal Fields. From 1900 until the 1950's, rock-asphalt was used extensively in Kentucky and elsewhere for road surfacing and was regarded widely as a premium-grade …

Electronic Computer Program For The Solution Of Slope Stability By The Wedge Method Of Analysis., James O. Boardman

Civil Engineering ETDs

Earth embankments and the foundation upon which they rest are subject to abear stresses induced by their own weight. It the embankment serves as a water retention structure, additional shear stresses are developed by seepage forces originating from pore pressure, from the reservoir pool and from rainfall. In certain regions, earthquake forces must also be added to these gravity and water forces.

Prior to the turn or the century and tor thirty some years after, earth dam side slopes were selected on the basis of past experience in lieu of a theoretical analysis. Justin, a noted authority on earth dam …


Stage-Fall-Discharge Relations For Flood Flows Over Highway Embankments, Gaylord V. Skogerboe, M. Leon Hyatt, Lloyd H. Austin Mar 1966

Stage-Fall-Discharge Relations For Flood Flows Over Highway Embankments, Gaylord V. Skogerboe, M. Leon Hyatt, Lloyd H. Austin

Reports

At Utah State University, considerable effort has been devoted to the analysis of submerged flow at open channel constrictions. A method of analyzing submerged flow was first developed for a trapezoidal flume by Hyatt (1965). Later studies verified the method of analysis for a rectangular flume (Skogerboe, Walker, and Robinson, 1965) and Parshall flumes (Skogerboe, Hyatt, England, and Johnson, 1965). Because of the previous findings, it was felt this method of analyzing submerged flow could be applied to highway embankments.

A highway embankment is a form of broad-crested weir when overtopped by flood waters. Being a weir, the flood discharge …

Impact Of I 75 On The Local Economy Between Walton And Georgetown, Robert C. Deen Feb 1966

Impact Of I 75 On The Local Economy Between Walton And Georgetown, Robert C. Deen

Kentucky Transportation Center Research Report

In 1956 the National Interstate and Defense Highway System was approved by Congress. It was immediately apparent that the diversion of traffic to such a system could result in immediate and lasting significant changes in the traffic flow patterns on the older highways, and this probably would have an immediate effect upon the businesses located along these older highways. In the bill authorizing the Interstate Highway System provision was made for studies of the economic effects of the new system upon local economies. The study reported herein is a part of a long-range investigation of the various aspects of economic …

Piggery Septic System, N E. Macintyre Jan 1966

Piggery Septic System, N E. Macintyre

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

ONE of the problems of intensive houses for pigs is the disposal of the dung and urine.

If proper arrangements are not made to remove this, it soon accumulates in an offensive pile at one end of the piggery, making an excellent breeding ground for flies.


Termites Or White Ants, Clee Francis Howard Jenkins Jan 1966

Termites Or White Ants, Clee Francis Howard Jenkins

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

TERMITES are commonly but erroneously called "white ants."

Actually they are more nearly related to cockroaches than to ants, but their general appearance and subterranean habits have given strong support to the popular designation.

They may be divided into two major groups from an economic point of view, viz., wood-dwelling and earth-dwelling termites.


Composite Pavement Design, James H. Havens Jan 1966

Composite Pavement Design, James H. Havens

Kentucky Transportation Center Research Report

There is an aura of superiority attached to the work "composite"--that is to say, the composite of anything is expected to be superior to its distinct elements of parts. It will suffice here to define a composite pavement as being compounded of "rigid" and "flexible" parts or layers. In reality, we mean layers of portland cement concrete and bituminous concrete--each of which is admirably sufficient in itself or may be so down-graded to satisfy lesser desires. Even so, we seem always to be discontent with the status quo. We are all somewhat opinionated on matters of pavement design and …


The Effect Of Epoxy Resin In Stone And Slag Concrete, James Chun-Min Chou Jan 1966

The Effect Of Epoxy Resin In Stone And Slag Concrete, James Chun-Min Chou

Masters Theses

"In concrete construction, the weight of the structure represents a large portion of the total load carried; thus, there is considerable advantage in reducing the weight of the concrete. To obtain this result, there are at least three approaches (1). The first method of producing lightweight concrete is by means of substituting a porous lightweight aggregate of low specific gravity for the ordinary aggregate. The second method relies on introducing large voids within the concrete or mortar mass; this is known as aerated, cellular or gas concrete. The third method is simply to omit the fine aggregate from the mix …

Subcritical Flow Over Various Weir Shapes, M. Leon Hyatt, Gaylord V. Skogerboe, Lloyd H. Austin Jan 1966

Subcritical Flow Over Various Weir Shapes, M. Leon Hyatt, Gaylord V. Skogerboe, Lloyd H. Austin

Reports

Submerged flow exists for any given structure when a change in flow depth downstream from the structure causes a change in flow depth upstream from the structure for any given constant value of discharge. The two flow depths, normally measured when submerged flow exists, consist of a depth upstream from the structure, which is used also for free flow conditions, and a depth of flow located any place downstream from the structure. The initial studies in which the submerged flow analysis was developed were made on flat-bottomed flumes (Hyatt, 1965; and Skogerboe, Walker, and Robinson, 1965). Later studies verified the …


Evaluation Of Free And Submerged Flow Data For Large Parshall Flumes, M. Leon Hyatt, Gaylord V. Skogerboe Jan 1966

Evaluation Of Free And Submerged Flow Data For Large Parshall Flumes, M. Leon Hyatt, Gaylord V. Skogerboe

Reports

Because the accurate measurement of water plays such an important part in water management, such structures as weirs, orifices, calibrated gates f and flumes have been developed. These structures provide the means for reasonable measurement of the smaller flows (1: .. 100 cfs), but for the large flows (100-3,000 cfs) the current meter, large Parshall flume, and various other flumes are commonly used. Where a permanent structure is required, the most widely accepted and utilized method for measurement of large flows is probably the Parshall flume. The purpose of this report has been to collect the existing flow data for …

Mathematical Hydraulics Of Surface Irrigation, Cheng-Lung Chen Jan 1966

Mathematical Hydraulics Of Surface Irrigation, Cheng-Lung Chen

Reports

The general hydrodynamic equations for a spatially varied unsteady flow in a prismatic open channel having an arbitrary cross-sectional shape can be derived from the equations of continuity and momentum. The assumptions based on the general concept of hydrodynamics and the theory of shallow water is introduced. The mathematical models in the surface irrigation can be formulated by these equations of motion with the appropriate initial and boundary conditions prescribed at the singularity point (the origin in the x, t-plane) and at x = 0. Therefore, the flow in the surface irrigation must be described by solving the boundary-value problem …

Application Of Electronic Analog Computer To Solution Of Hydrologic And River Basin Planning Problems: Utah Simulation Model Ii, J. Paul Riley, Duane G. Chadwick, Jay M. Bagley

Reports

As demands upon available water supplies increase, there is an accompanying increase in the need to assess the downstream hydrologic system. At Utah State University this problem is being approached by electronic analog simulation of the hydrologic system. Modeling concepts are based upon the development of basic relationships which describe the various hydrologic processes. Within a system, these relationships are linked by the continuity -of-mass principle which requires a hydrologic balance at all points. Once established, the model is applied to any particular geographic unit by determining the appropriate constants of the hydrologic equations. The analog computer is ideally suited …

Checking Rigid-Framed Structures By Extended Moment-Area Equations, Lucky Li-Chi Chow

Masters Theses

"Using the known moments obtained from the moment distribution solution, the extended moment-area equations are used to check whether or not delta x, delta y, delta theta are truly zero, or are any other quantity they are supposed to be. In order to get a reasonably correct answer, a solution must meet both the elastic checks and the static checks for their equilibrium and compatibility functions. Using the extended moment-area equations, the magnitudes of the slopes and deflections at all of the joints in framed structures can be found easily"--Abstract, page ii.
