Mass Transfer To Drops Moving Through Power Law Fluids In The Intermediate Reynolds Number Region, Robert M. Wellek, Türker Gürkan Jan 1976

Mass Transfer To Drops Moving Through Power Law Fluids In The Intermediate Reynolds Number Region, Robert M. Wellek, Türker Gürkan

Chemical and Biochemical Engineering Faculty Research & Creative Works

The mass transfer rate to fluid spheres is calculated for power law and Newtonian fluids by using the intermediate Reynolds number stream functions of Nakano and Tien (1970) and Yamaguchi et al. (1974), respectively. The Sh increases with increases in Re and Pe and decreases in n. Better results are obtained with Nakano and Tien's functions when Re > 10 and with Yamaguchi's functions when Re < 10. Copyright © 1976 American Institute of Chemical Engineers

Process Optimization By Flow Sheet Simulation, L. D. Gaines, J. L. Gaddy Jan 1976

Process Optimization By Flow Sheet Simulation, L. D. Gaines, J. L. Gaddy

Chemical and Biochemical Engineering Faculty Research & Creative Works

Optimization of large or complex chemical processes often requires simplifying the system to reduce the mathematics to a form manageable by available algorithms or to reduce the time required to perform the computations. In many cases, such simplification alters the solution of the problem. Flow sheet simulation programs are ideally suited to the study of chemical processes, although the computational time is generally considered excessive for detailed optimization of complex systems by the usual procedures. This paper discusses the modifications needed to apply flow sheet simulation programs to the optimization of chemical processes. The advantages and disadvantages of the use …

Computer Analysis Of 3-Phase Induction Motor Operation On Rural Open-Delta Distribution Systems, Stephen C. Seematter, Earl F. Richards Jan 1976

Computer Analysis Of 3-Phase Induction Motor Operation On Rural Open-Delta Distribution Systems, Stephen C. Seematter, Earl F. Richards

Electrical and Computer Engineering Faculty Research & Creative Works

Open-delta/open-delta and open-wye/open-delta transformer banks are often used as an economic means of supplying simultaneous single-phase and 3-phase loads in rural areas. If the 3-phase load is an induction motor, the inherent voltage unbalance causes increased losses and uneven heating that may lead to motor failure. Often these motors are submersible or deep well pump motors located in remote unattended areas or air conditioning motors which may not have sufficient over-design to handle the voltage unbalance. The theory analyzing the open-delta distribution system has existed for many years, however, because of the tedious and almost infinite differences in distribution topology, …

A Computer Graphics Analysis Of A Freeway Merge Control System, Thomas Alan Risher

Retrospective Theses and Dissertations

In 1975, C.S. Bauer completed a doctoral dissertation at the University of Florida which treated the Green Band Merging Control System on I-75 in Tampa, Florida. In this work, Bauer suggested the possibility for the use of computer graphics as a toll for analysis of the bands generated by the Green Band Control System Simulation developed in his dissertation. The use of computer generated movies of the bands displayed to ramp drivers by the system allows the comparison of various band control strategies without the need for field implementation and testing. With the goal of producing such films in mind, …

A Simulator For The Motorola M6800 Microprocessor, Carolyn Elizabeth Jordan

Retrospective Theses and Dissertations

The Motorola Company has developed a microprocessor called the M6800 Microprocessor. While the microprocessor is being configured, it is general practice to develop the software at the same time. This is where simulation of the proposed hardware operation can become very important to the success of the design effort. The simulator duplicates the microprocessor execution of machine language instructions on another computer. The simulator discussed in this paper is denoted the SIM6800. The purpose of this paper is to describe the structure, coding, and execution of the SIM6800 simulator. A User's Guide and sample program have been included.

Mass Loadings Of Selected Water Quality Parameters For The State Of Florida, Charles D. Miller Jan 1976

Mass Loadings Of Selected Water Quality Parameters For The State Of Florida, Charles D. Miller

Retrospective Theses and Dissertations

The mass loadings of pollutants common in surface waters result from the discharges of many different sources. In the last few years it has been noted that nonpoint sources contribute more pollutants than point sources. This is because in many cases the point source discharges have been, by law, reduced drastically. In the State of Florida many water quality parameters were examined to estimate the mass loadings in streams related to, drainage area, average flow, land use, soil type and management practices. A total of sixteen streams were examined. The information was first calculated for mass loadings as a function …

Multicoupled Bandpass Filter Design Using A Multiple Feedback Configuration, Robert J. Martin Jan 1976

Multicoupled Bandpass Filter Design Using A Multiple Feedback Configuration, Robert J. Martin

Retrospective Theses and Dissertations

In this paper, two methods for the design of active analog feedback bandpass filter pairs are examined. A third method is presented that does not use extra amplifiers for summation nor multicoupling. This third method uses identical bandpass amplifies and employs resistor summing to provide multicoupling. The name of this configuration is the "Dual Amplifier Bandpass Filter Employing Resistor Summing" (DABFERS). This configuration is economically attractive, has low sensitivity and better phase lag characteristics. In addition, third order prototypes are examined and a solution method for higher order prototypes is suggested.
