Energy, Environment And Incremental Decision Making, Jeff V. Conopask, Robert R. Reynolds Jr.

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

During the late 1960's and early 70's a variety of environmental/energy oriented legislation was enacted by the Congress. The most important of these acts, the National Environmental Protection Act (NEPA), required that environmental impact statements be filed when various private and public activities have a potential for impacting man and his environment. (17) Impact statement requirements go beyond the currently practiced cost/benefit analysis, which is often just a production (direct) impact assessment. Heretofore, indirect or second round economic and social effects of consequence affecting other national goals were seldom counted.

The Design And Performance Of A Distributed Flow Water-Cooled Solar Collector, Donald L. Spencer, Theodore F. Smith, Herbert R. Flindt

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Design of a flat plate collector which reduces the temperature differential between the absorber plate and the fluid is described. The reduced temperature differences are shown to yield increase collector performance. Flow characteristics of the collector are examined. Collector thermal performance is illustrated for typical operating and environmental conditions. A cost analysis is presented to demonstrate that material and assembly costs are substantially lower than for any collector presently on the market.

The Application Of Water Jets In Coal Mining, David A. Summers

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Water is one of the natural erosion agents which through time has changed the face of the earth. Application of this principle to remove earth and rock by man is a long established technique. This paper briefly describes the changes in technology which have brought the application of water jets from the slow erosion of soil to the point where in Canada some 3,400 tons per shift are currently mined in a coal mine using high pressure water jet technology. The use of water jets has shown sufficient promise that there are several research programs currently being funded by the …

Direct Ac Generation From Solar Cell Arrays, Fernando L. Alvarado, Adel H. Eltimsahy

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Results of the investigation of the performance of solar cells when directly coupled to a conventional three-phase power network are presented. This approach dissociates the electricity production problem from the electric energy storage problem. Extensive studies of the required power inverter are performed. Preliminary simulation results indicate that ac power outputs of better than 90% of the optimum cell power output can be easily achieved by means of a suitably controlled inverter, thereby justifying the elimination of dc loads or local dc electric energy storage devices. It is also shown that the controlling policy for the inverter must depend on …

Dynamic Simulation For Regional Energy Studies, B. W. Jones, P. M. Moretti, J. H. Mize

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

A series of models has been developed for regional studies of energy supply- demand systems. The models are based on dynamic simulation of components of the system using equations derived from the technical details of the system. The models contain sufficient detail to make in-depth studies and specific recommendations. The final goal is to include all aspects of regional energy systems from native supplies of energy resources to the economic activities of the region.

To develop a comprehensive model, the system has been partitioned into subsystems, so that a detailed model can be made for each subsystem. The detailed model …

How Might Synthetic Fuels From Coal Affect Natural Resources And Environment?, H. J. Plass Jr.

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Energy self-sufficiency for the U. S. requires substantially increased use of coal. Direct combustion of coal without adequate environmental controls, as would occur if coal were used as a fuel for homes and offices throughout the country, would result in severe air pollution problems„ Synthetic fuels from coal such as methane, low BTU gas, or hydrogen, when utilized by the homes and businesses as gas or as electricity from gas, will contribute a much smaller amount of air pollution. However, to make these synthetic fuels available, it is necessary to mine more coal than would have to be mined for …

Two-Dimensional Analysis Of The Coherent Instationary Motion Induced By An Obstacle, Using Electrochemical Methods, B. Py, C. Tournier

Symposia on Turbulence in Liquids

The non stationary flow induced by a cylinder with a square cross-section was studied on the cylinder's surface and in the wake with two different electrochemical probes. On the cylinder was mounted split rectangular electrodes with high enough aspect ratio so as to measure the chordwise component of the wall shear stress with its sign. The non-linear response of this transducer was studied. In the wake, the longitudinal component of the velocity was obtained with conical electroactive elementswhich are mainly sensitive to this component.

The fluctuating coherent components are separated from the aleatory part of the signal and then decomposited …

On The Role Of Conditional Averages In Turbulence Theory, R. J. Adrian

Symposia on Turbulence in Liquids

It is shown that conditional averages in the form of expected values of functions of the velocity at an arbitrary point given the velocities at a finite number of distinct points, appear naturally in certain types of turbulence theories and that the closure problems in such theories ultimately reduce to the approximation of these averages. Two exemplary theories are considered. The first is characteristic of turbulence models formulated in terms of probability density functions whereas the second is related to the derivation of optimal algorithms for the numerical integration of the turbulent Navier-Stokes equations at large Reynolds numbers. Some mathematical …

Continuous Purlin Tests, Teoman Peköz

CCFSS Library (1939 - present)

INTRODUCTION The results of the first phase of an experimental investigation are presented in this report. The objective of this investigation is to study the applicability of a theoretical approach developed at Cornell and implemented in a computer program developed by T. Pekoz for Diaphragm Braced Channel and Z-Section Purlins. In this phase of the experimental program three "full-scale" assemblies were tested under simulated wind-uplift loading. In addition, several supplementary tests were carried out to determine various physical parameters utilized in the analytical solution. The reported results are restricted to those tests that have direct bearing on correlating the test …

Alcohol Assisted Hydrocarbon Fuels: A Comparison Of Exhaust Emissions And Fuel Consumption Using Steady-State And Dynamic Engine Test Facilities, D. J. Bushnell, J. M. Simonsen

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

This paper presents experimental data which exemplifies the differences in emission level testing on internal combustion engines when dynamic engine tests are used instead of steady-state engine tests. A comparison of the two test methods is made using hydrocarbon fuels with varying amounts of methanol. Emissions measured include the nitric oxides, unburned hydrocarbons and carbon monoxide. Emission levels and fuel consumption are reported for the various volumetric percentages of methanol in the fuel.

Of special significance are the different trends the emission levels establish when subjected to a dynamic engine test as compared to the results for the steady-state tests. …

A Seismic Investigation Over A Near-Surface Cavern, Richard D. Rechtien, David M. Stewart

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

A field experiment was conducted over a near-surface cavern with the principal objective of obtaining a spatial definition of the associated Cavity Resonance phenomenon, as reported by Watkins et. al. (1967) and by Godson and Watkins (1968). The results of the experiment were inconsistent with those of the earlier investigators in that all seismic events recorded in the vicinity of the cavity, having vertical velocity components, could be readily identified as standard modes of seismic wave transmission. A persistence of strong horizontal motion was observed for late record times. This horizontal motion was consistently oriented parallel to the cavity boundary, …

Subsolidus Equilibria And Metastable Phase Development In The System Zro₂-Al₂O₃-Sio₂, Charles Christopher Sorrell

Bachelors Theses

"Subsolidus equilibria in the low silica portion of the system ZrO₂-Al₂O₃-SiO₂ were studied by X-ray diffraction of quenched samples fired at 1300°, 1400°, and 1480°C. Samples prepared as powders from combinations of a-Al₂O₃, Al(OH)₃, silicic acid, ZrO₂, and kaolinite reacted very slowly at 1300° and 1400°C and the trends toward equilibria are not apparent. A mixture of zircon and Al(OH)₃ reacted slowly at 1480°C to form mullite and ZrO₂, indicating that the latter phases are the stable assemblage rather than zircon and alumina. A gel prepared from aluminum nitrate, zirconyl nitrate, and colloidal silica reacted at 1480°C to form alumina, …

An Analysis Of The Role And Effectiveness Of The Contract Manager In Government Contracting., Daniel Martin Wilson

Masters Theses

"The contract manager in carrying out the contract management function of government contracting represents a vital element of the procurement process. He is charged with responsibilities for assuring that a product or service is delivered in a timely manner and is of specified quality, quantity and price. However, research and a survey of his role reveal that he is regarded a s a functional specialist, guided by a mass of procedural requirements, and he is not included in the managerial hierarchy of contracting.

Because his role does not accord him the status or authority commensurate with the importance of the …

Estimation Of Vehicle Transfer Functions., Leonard Francis Laskowski Iii

Masters Theses

"This study is an investigation of several techniques used to estimate lateral control models for vehicles. The lateral control model that was identified related steering wheel angle input to lateral acceleration output. Two different order models were identified, one a biquadratic and the other a fourth order lowpass system with second order numerator dynamics. The two main approaches investigated were:

1) Regression analysis

2) Fast Fourier Transform Techniques These techniques were chosen because of their inherent immunity to noise.

A CSMP simulation of all identified models was then made to determine their validity. These checks were made using laboratory data …

System Reliability: Exact Bayesian Intervals Compared With Fiducial Intervals, Kathryn P. Berkbigler, James K. Byers

Computer Science Faculty Research & Creative Works

This paper compares numerically two different, widely used lower limit estimates for the reliability of a series system: Bayesian limits and fiducial limits. The fiducial limits are obtained by Monte Carlo simulation because of its simplicity and ease of computer programming. Subsystem failures are s-independent and exponentially distributed; life test data are available for estimating the failure rate of each system.

We develop the theory of mod 2 Stiefel-Whitney homology classes for Euler polyhedral. We then describe a simple method of obtaining pJ. bordism theories. Finally, we define the ungraded bordism theory of Euler spaces and show that it is isomorphic to ordinary total homology. © 1975 American Mathematical Society.

Mechanical Degradation Of Dilute Solutions Of High Polymers In Capillary Tube Flow, John D. Culter, Jacques L. Zakin, Gary Kent Patterson

Chemical and Biochemical Engineering Faculty Research & Creative Works

Experimental results on mechanical degradation in capillary tubes of polyisobutylene polymers in dilute solution are described. In laminar flow, degradation is independent of tube length, indicating that entrance effects are dominant. This shows that capillary experiments do not yield explicit information on the effect of shear stress on mechanical degradation. In turbulent flow, large entrance effects are also observed, but some degradation does take place in the fully developed flow region. Copyright © 1975 John Wiley & Sons, Inc.

Quantitative Overdesign Of Chemical Processes, R. A. Freeman, J. L. Gaddy

Chemical and Biochemical Engineering Faculty Research & Creative Works

Overdesign is applied to chemical processes to account for expected variations in the design data or design conditions. These variables must be treated quantitatively in order to design a process that is certain to perform adequately. Process dependability is introduced as a means of quantifying variable process behavior. Overdesign using the dependability criterion is a stochastic optimization problem. An example problem with three stochastic variables and two design variables is presented to illustrate these procedures. Copyright © 1975 American Institute of Chemical Engineers
