A Mathematical Model For Determining The Thermal Distribution Resulting From Discharge Of A Heated Effluent, Alan H. Epstein Jan 1972

A Mathematical Model For Determining The Thermal Distribution Resulting From Discharge Of A Heated Effluent, Alan H. Epstein

Retrospective Theses and Dissertations

A mathematical model is presented for the problem of determining the two-dimensional temperature distribution resulting from the discharge of a heated effluent into a shallow, quiescent receptacle. The physical model of the problem is the two-dimensional jet augmented by an imposed condition of viscous drag due to bottom friction effects. By virtue of the assumption that the physical properties of the effluent are independent of temperature over the operational temperature range of the plume, the analysis separates the total problem into a flow problem and a temperature problem. Solution of the temperature distribution is accomplished both analytically and numerically. Analytically, …

Suppression Of Turbofan And Turbojet Engine Generated Noise, Harry David Master Jan 1972

Suppression Of Turbofan And Turbojet Engine Generated Noise, Harry David Master

Retrospective Theses and Dissertations

Every advance in the transformation of heat energy into mechanical energy has involved a noise problem, and in general it increases with the power production. The jet airplane is a good example: the large-scale turbulence of the exhaust gases in the jet forms an unusually intense source of sound the control of which is quite difficult. The additionally generated fan noises add characteristic fan tones which are particularly noticeable on landing approaches. the human ear is the vulnerable receiver of these noises, and the problem becomes one of deciding how much jet engine noise reduction is required for the comfort …

Computer Method For Airport Noise Exposure Forecast, John Michael Bateman Jan 1972

Computer Method For Airport Noise Exposure Forecast, John Michael Bateman

Retrospective Theses and Dissertations

The major problem facing air transportation for the next decade is aircraft noise. The noise level due to the operation of large jet aircraft has created a very serious annoyance problem to the people living near of adjacent to jet airports. The noise problem has developed both for take-off and landing operations of these aircraft with take -off noise causing the greatest annoyance factor. A technique called Noise Exposure Forecast (NEF) has been developed to identify the annoyance factor of these noises to people and activities on the ground. With these NEF ratings or numbers, planners can better determine the …

Optimization Analysis Of A Simple Position Control System, Arthur G. Cannon Jan 1972

Optimization Analysis Of A Simple Position Control System, Arthur G. Cannon

Retrospective Theses and Dissertations

One of the problem areas of modern optimal control theory is the definition of suitable performance indices. This thesis demonstrates a rational method of establishing a quadratic performance index derived from a desired system model. Specifically, a first order model is used to provide a quadratic performance index for which a second order system is optimized. Extension of the method to higher order systems, while requiring more computations, involves no additional theoretical complexities.

Flood Control Modeling, Peter E. Delle Donne Jan 1972

Flood Control Modeling, Peter E. Delle Donne

Retrospective Theses and Dissertations

This is a research report that discusses some continuous and discrete modeling techniques. The report applies these techniques to the analysis of Canal 38 (Kissimmee River) part of Central and South Florida Flood Control District. The analysis is based on recorded data for defining the physical systems parameters. Established parameters are mathematically related to define a descriptive model for Canal 38. The modeling procedure of 'trial and error' is used to assemble the model with measures of merit, the integral square error, and root mean squared error. General simulation considerations are discussed for application of the mathematical model.

An Investigation Of Methods For Reuse Of Rubber Tires, Charles Edward Armbruster Jan 1972

An Investigation Of Methods For Reuse Of Rubber Tires, Charles Edward Armbruster

Retrospective Theses and Dissertations

Methods of reusing/recycling the more than 250 million automobile and truck tires which are worn out each year were investigated. The existing methods of reusing tires account for about 30 percent of the volume of scrap tires generated each year. These methods are, Retreading, Reclaiming (by reducing to ground up rubber and fiber), and Tire Splitting (stamp items out of sidewall and tread areas). Several possibilities for reusing/recycling the unused 70 percent were discovered. These methods are as follows: Destructive Distillation -- a method of recovering chemicals from tires by pyrolitic action. It is anticipated that eventually as much as …

Theoretical Predictions Of Flow Profiles In Capillary Blood Vessels, Eileen Hallman Jan 1972

Theoretical Predictions Of Flow Profiles In Capillary Blood Vessels, Eileen Hallman

Retrospective Theses and Dissertations

The purpose of this thesis is to illustrate the nature of blood flow within capillaries by using familiar mathematical techniques. Because the circulatory system is so complex, the fluid dynamics of the system is prefaced by a discussion of the circulatory physiology in terms of geometry and physics. The understanding of the basic structures and functions of the circulatory components necessarily precedes the justification of assumptions. Several mathematical models which attempt to describe the fluid dynamics of blood flow phenomena are presented and discussed. The results of these models are correlated with existing experimental data in order to determine which …
