Temperature Fluctuations Within A Solid Of Finite Thickness, William Sanford Hogan Jan 1950

Temperature Fluctuations Within A Solid Of Finite Thickness, William Sanford Hogan

Masters Theses

"The object of this thesis is to determine by analytical methods the temperatures within a homogeneous plate of finite thickness subjected to a constant temperature on one side and a periodically fluctuating temperature on the opposite side. The heat flow in the other two directions is considered negligible in this problem. Periodic changes of temperature are frequent in nature and in engineering. The surface of the earth is heated periodically by the sun in its daily and annual cycle and the periodic temperature changes below the surface and the question to which depth these changes are appreciable were dealt with …

The Application Of The Relaxation Method To The Solution Of Steady-State Heat Transfer Through A Concentric Square Insulator, William Edward Simpkin Jan 1950

The Application Of The Relaxation Method To The Solution Of Steady-State Heat Transfer Through A Concentric Square Insulator, William Edward Simpkin

Masters Theses

"It is the object of this thesis to express the relationship between the heat transfer through a square insulator of variable inside-outside dimension ratios, in terms of a concentric round insulator of the same inside-outside diameter ration, by means of a continuous curve. Mathematically speaking, this thesis will have a plot of a variable coefficient, cs, to be used...in terms of the ratio of the width of the outside square to the width of the inside square"--Statement of Problem, page 8.


The Temperature Within A Homogeneous Plate Of Finite Thickness, Charles R. Remington Jan 1950

The Temperature Within A Homogeneous Plate Of Finite Thickness, Charles R. Remington

Masters Theses

"The object of this thesis is to determine by an analytical method the temperature within a homogeneous plate of finite thickness subjected to a constant temperature on one side and a periodic fluctuating temperature, expressible in a Fourier series, on the opposite side. This problem in periodic temperature changes has not, to the author's knowledge, been solved previously. The flow of heat in the problem is considered in only one direction, the x-direction. Flow in the other two directions is considered negligible, or zero. Periodic temperature changes in the earth are of importance. The temperature changes have been used by …

Test 414: Ustrac Model 10-A, Nebraska Tractor Test Lab

Nebraska Tractor Tests

All tractors tested at the Nebraska Tractor Test Laboratory were certified by their manufacturers as being stock model machines, conforming to specifications filed with the application for test. No special or high-test fuels were used except as recommended by the manufacturer as necessary. All results within the official tractor test report were actually attained in tests and are without correction or allowances for friction, temperature, altitude, etc. The results were initially accomplished with the tractor in charge of skilled operators employed by the University. Unless otherwise noted, each tractor was apparently in good condition at the end of the testing …
