Binary Nucleation. Ii. Time Lags, Gerald Wilemski

Physics Faculty Research & Creative Works

The role of the time lag needed to attain steady state nucleation in binary vapors is discussed. Under appropriate conditions it is possible to obtain both a large predicted rate of binary nucleation and a large time lag. In this circumstance, homogeneous nucleation of the more concentrated component may be the predominant process. It is of obvious importance to the experimentalist to differentiate between these possibilities. Approximate formulas for the time lags are developed, and representative calculations for the ethanol-water system are reported.

Binary Nucleation. I. Theory Applied To Water-Ethanol Vapors, Gerald Wilemski

Physics Faculty Research & Creative Works

A quantitative study of nucleation in vapor mixtures of ethanol and water near 273°C is presented. First, Reiss' theory of binary nucleation is reexamined. The theory is modified slightly in order to yield the proper limit for homogeneous nucleation in a one-component system. Moreover, a corrected expression for the equilibrium concentration of mixed clusters is derived. Calculations of the critical vapor activities needed to produce a visible condensate are presented and compared with the results of Flood's cloud chamber experiments. The agreement is only fair, but qualitative accord is found.

Differential Cross Sections For Elastic And Inelastic Scattering Of 15-100-Kev Li⁺ By He, John T. Park, Victor Pol, James E. Lawler, Jacob M. George, John E. Aldag, John W. Parker, Jerry Peacher

Physics Faculty Research & Creative Works

Sets of energy-loss spectra for Li⁺ incident on He that were taken at a series of scattering angles were used to calculate differential cross sections. Differential cross sections are given for elastic scattering and for excitation of the He (n=2) states. The differential cross section is also given for excitation of states corresponding to a 60-eV energy loss. These inelastic differential cross sections exhibit maxima at scattering angles greater than zero. The velocity dependence of the cross sections can be compensated by displaying the elastic data in ρ-vs-τ plots and the inelastic data in ρ-vs-E^3/2θ plots. When …

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 …

On Functional Equations Related To Mielnik's Probability Spaces, C. F. Blakemore, Caslav V. Stanojevic

Mathematics and Statistics Faculty Research & Creative Works

It is shown that the method used by C. V. Stanojevic to obtain a characterization of inner product spaces in terms of a Mielnik probability space of dimension 2 does not admit a generalization to dimension n > 2. © 1975 American Mathematical Society.

Stiefel-Whitney Homology Classes And Bordism, Ethan Akin

Mathematics and Statistics Faculty Research & Creative Works

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.

Using Ibm's Information Management System To Implement A Relational Data Base, Melvin Arthur Rushton

Masters Theses

"A relational model of data has been the topic of several papers which deal with the question of the underlying design philosophy of data base systems. E. F. Codd, C. J. Date, and others have discussed the application of relation theory to formatted data, the objectives of such an approach, normalization of relations, and languages for manipulating the model (data sublanguages). Few papers have delt with storage constructs or access techniques for a relational data base. Indeed, it was not necessary that they do so, for the user of such a system is only concerned with the information available in …

Toacs : An Interactive Computer Graphic Display Model Of A Theaterwide On-Line Air Combat Simulation, Herman William Blick

Masters Theses

"On-line interactive graphics is a very effective research tool for examining the concepts, components and design parameters of theater warfare involving multiple aircraft. The aim of the present research is to design an on-line computer system which utilizes interactive graphic displays to develop a dynamic, two-sided mathematical model of theaterwide tactical fighter combat operations. The model, called TOACS, is very useful in simulating and evaluating airborne defense systems and the problems common to this type of simulation — such as the formulation of battle strategy for the commitment and guidance of interceptors against threat aircraft -- as well as those …

Tertiary Welded Tuffs Of The Ryan Spring Area, Needle Range, Beaver County, Utah, Peter Carlyle Rauch

Masters Theses

"The Needle Range of southwestern Utah is composed of Paleozoic sediments overlain by a thick sequence of Tertiary volcanic rocks primarily of the welded tuff class. The area has undergone at least four stages of post-eruptive structural deformation. The most significant stage is that which formed the range by normal Basin and Range type faulting. The faults strike northwest and tilt the volcanic layers northeast.

The volcanic section is composed primarily of the Needles Range Formation (Oligocene) overlain by the Isom Formation and underlain by several flows and ash flows, one of which has been tentatively correlated to the Escalante …

A Study Of Middle To Late Quaternary Sediments In The Karst Trap., David Lewis Rath

Masters Theses

"Quaternary deposits preserved in a karst trap on the Lebanon uplands a e described. The sediments represent the Yarmouthian, Illinoian, Sangamonian, and Wisconsinan Stages. The karst trap is pre-Yarmouthian in age. The lowermost deposit consists of residual fill material on which lies a well-developed Yarmouth paleosol. During the Illinoian Stage about 61 cm (2 feet) of Loveland loess was deposited over the area. Toward late Illinoian conditions favoring erosion rapidly filled the closed system, stripping the loess and reducing the residual slopes. The system stabilized during the Sangamonian Stage allowing for a thick, strong Sangamon paleosol to deve lop on …

It then shows these principles to be universal and finally discloses the different environmental constraints that evolved and concludes that they are universal, but their applicability is to a certain extent possible and highly dependent on the …

An Experimental Study Of Mass Transfer To Droplets In Aqueous Polymer Solutions., Richard Gerard Schafermeyer

Masters Theses

"Instantaneous and time-average mass transfer coefficients for 1 the free-fall period was obtained for transfer of iodine from nonNewtonian continuous phases to carbon tetrachloride drops. The nonNewtonian continuous phases were aqueous solutions of carboxymethyl cellulose and carboxy polymethylene. Although a few exceptions were found, the continuous phase mass transfer coefficients were, in general, found to decrease with increasing time of drop contact. Comparisons of the experimental data to theoretical relations showed that changes in drop internal circulation probably occurred for that data which showed a time effect for the mass transfer coefficient. Several explanations for the time effect were offered, …

Decoupled Explosive Charge Effects On Blasting Performance, Roberto Ucar

Masters Theses

"This investigation was performed to determine the burden at which hard rock would break utilizing decoupled and unstemmed charges when the free surface parallel to the borehole was the wall of an open hole. This open hole was created by burn cuts and by drilling holes of 7-7/8 in. and 12 in. diameter. Additional tests were performed using partially stemmed charges where the stemming was the same size as the explosive charge.

The explosive used was a 0.75 lb. slurry charge, 1.5 in. diameter and 10 in. long. The diameter and depth of the borehole were 2 in. and …

Computer Simulation Of Radiation Effects In Fe₃Al By Using Alternating Direction Implicit Numerical Techniques., Dean Lewis Tibbitts

Masters Theses

"An analysis was conducted to see if the alternating direction implicit (a.d.i.) numerical technique could be applied to a many-body dynamical radiation damage model.

The computer program which resulted was named ADI. It was numerically stable for small time steps used in conjunction with low ev knock-ens. It was also able to relax the a toms in the system simultaneously in the implicit direction. However, an existing explicit computer code, which was to be replaced by ADI, proved to be more numerically stable and about 40% faster"-- Abstract, p. ii
