Transient Convective Heat Transfer In Closed Containers During And After Gas Injection, Jennings Donell Means Apr 1973

Transient Convective Heat Transfer In Closed Containers During And After Gas Injection, Jennings Donell Means

Theses and Dissertations

This dissertation presents experimental data correlations for the spatially - averaged convective heat transfer coefficient for thin walled closed containers during and after gas injection. The different modes of heat transfer were identified, and correlations were made for each. Correlations are presented for the injection period, post-top injection, post-bottom injection, post- tangential, post-radial injection, and post-ejection heat transfer for various tank geometries. Of special significance are the very high heat transfer rates that were shown to be present in some cases immediately after injection. Heat transfer rates were shown to be, for a short period, up to almost two orders …

The Design And Analysis Of An Electro-Pneumatic Signal Converter, Richard K. Thornton Apr 1973

The Design And Analysis Of An Electro-Pneumatic Signal Converter, Richard K. Thornton

Theses and Dissertations

In the field of process control it is desirable to study dynamic characteristics such as frequency response and distortion when determining just how equipment is to be controlled. Pneumatic controllers, transmitters, control valves, etc., all have dynamic behaviors which can be expressed mathematically as transfer functions. Each component plays an important role in determining the entire system behavior. Frequency response is one technique used in developing a component’s transfer function. By driving a device with a sinusoidal signal of fixed amplitude and frequency the output amplitude and phase shift are measured and compared with that of the input. Varying the …

Finite Conductance Element Method Of Conduction Heat Transfer, E. Clark Lemmon Apr 1973

Finite Conductance Element Method Of Conduction Heat Transfer, E. Clark Lemmon

Theses and Dissertations

One of the basic goals in engineering is to formulate models which will provide a means for analytically predicting observed phenomenon. For some time, the partial differential equations describing the steady state and transient conduction of heat within a solid have been available. However, the straight forward use of these equations is often restricted due to the surface geometry of the solid. If the surface geometry is at all irregular, exact solutions will in general not exist. In that case, a solution is sought by some approximate numerical technique. The two techniques most often used are the finite difference method …

History Of The Swiss American Historical Society, Heinz K. Meier Feb 1973

History Of The Swiss American Historical Society, Heinz K. Meier

Swiss American Historical Society Newsletter

On Independence Day 1927, on the occa sion of the Swiss Singing Festival, a group of Swiss Americans living in the Chicago area decided to found a historical society. The idea had been in the air, so to speak. For some time , persons of different background and living in different parts of the country had been working diligently in that direction by encouraging existing Swis s societies to add another dimension to their activities and by gathering materials about "famous Swiss." They were annoyed and concerned "by the fact that every outstanding person of Swiss origin was claimed by …

The Des Moines Rapids: A History Of Its Adverse Effects On Mississippi River Traffic And Its Use As A Source Of Water Power To 1860, Donald L. Enders Jan 1973

The Des Moines Rapids: A History Of Its Adverse Effects On Mississippi River Traffic And Its Use As A Source Of Water Power To 1860, Donald L. Enders

Theses and Dissertations

During the 19th Century, the Mississippi River was the chief commercial highway in the United States. But for two impediments, the Upper and Lower (Des Moines) Rapids, its entire course of 2400 miles would have offered an untroubled thoroughfare to watercraft.

The federal government, as well as private concerns, attempted throughout the better part of that century to alleviate the river of its barriers and to develop its rapids as a source of power. Those attempts were disappointingly unsuccessful, however, and not until the advent of the 20th Century, when the nation had matured both economically and technologically, was the …

Some Glimpses Of The Past: The Swiss Benevolent Society Of Chicago 1872-19972, Leo Schelbert

Swiss American Historical Society Newsletter

Only some 130 years ago Chicago, now a sprawling metropolis of the Midwest, began to grow from a small prairie seaport on lake Michigan into a thriving American city. Many Swiss immigrants followed the trail of the thousands of newcomers to the emerging town who either hailed from the Atlantic seaport states and from Midwestern rural communities or who had crossed the Atlantic to become settlers of the white man's New world. By 1870 the city counted some 298,977 inhabitants, at the same date some 1,435 Swiss had settled in Cook County, many of whom lived in Chicago.

Electron Cyclotron Radiation Measurements To Determine Relative Electron Temperatures In A Low-Density Magnetic-Mirror Plasma System, Andrew L. Gardner Feb 1972

Electron Cyclotron Radiation Measurements To Determine Relative Electron Temperatures In A Low-Density Magnetic-Mirror Plasma System, Andrew L. Gardner

Faculty Publications

Measurements of the electron cyclotron radiation emitted from the plasma of the Alice system were made using a synchronous detection microwave radiometer in the range of 10.2 - 11.6 GHz. Both sidebands were used to sample radiation from two nested closed shells within the plasma. For a tenuous plasma this radiation is proportional to the product of the electron density and the electron temperature. Since measurements of the plasma density were available from other detectors, relative values of the electron temperature were obtained using the measured radiation intensity.
