Numerical Analysis Of The Interaction Of An Oblique Shock Wave And A Laminar Boundary Layer, James K. Cole

Mechanical Engineering ETDs

When a shock wave impinges on a boundary layer the interaction involves the continuous, viscous behavior of a boundary layer with the almost discontinuous behavior of a shock wave. A boundary layer is the region of a moving fluid that is adjacent to a solid surface. The velocity of the fluid is zero at the surface. The viscosity of the fluid causes relatively large shearing stresses in boundary layers. A shock wave is a region of a fluid which has extremely large gradients of the particle velocity. Shock waves are often rep­resented by mathematical discontinuities. A shock wave is called …

Adaptation Of Beggs Deformeter Apparatus To The Solution Of Three-Dimensional Problems, Roland L. Finley

Mechanical Engineering ETDs

In the area of structural analysis and structural design, numerous efforts have been made and more are yet to be made toward solving statically indeterminate problems easily and with a high degree of accuracy. Fortunately, the great majority of such problems can be solved by one or more of the many mathematical methods that are normally used. However, the mathematical solutions become exceedingly difficult if and when it is desired to use irregularly shaped structural members.

The Control And Measurement Of Minute Curvatures In A Steel Shaft, Donald F. Wilkes

Mechanical Engineering ETDs

The primary purpose of this thesis was the solution of several special problems relating to the establishment, adjustment, and measurement of small elastic curvatures and the associated strains in a metal shaft. The solution of these problems was an important link in the development of a new type of seismometer for measuring extremely long periods with vibrations (up to 60 seconds). To achieve the sensitivity and long natural period of vibration required for accurate measurements of long-period waves, the seismometer employs a seismic mass which is suspended on an air film and constrained to follow an essentially horizontal guide rod. …

Shape Factors For Conduction Of Heat, Harry J. Otway

Mechanical Engineering ETDs

The purpose was to measure the heat conduction shape factors for cylinders and square prisms enclosed by spheres and to estimate the accuracy of the following approximation. This approximation is that of matching the area of the cylinder or prism to an equivalent sphere and then applying the analytical solution for concentric spheres.

Water Conservation On The Farm, John W. Lewis

Journal of the Department of Agriculture, Western Australia, Series 4

SMALL scale conservation of water for agricultural use is becoming increasingly important throughout Australia.

As land development intensifies, it is natural that farmers turn to more dams and earthen tanks for stock water and irrigation.

Adequate water is essential to supply the carrying capacities made possible by improved pastures, and where greater quantities of water can be stored, fodder crops, pastures, orchards and vegetables can be irrigated.

Australian Spark Arrester Tests : Test No. Spa-21 : Caterpillar D7 Turbocharger, W F. Baillie, G. H. Vasey

Journal of the Department of Agriculture, Western Australia, Series 4

FORMAL tests on spark arresters are conducted by The Tractor Testing Committee* at the Testing Station, Werribee, on behalf of those Companies concerned with tractors, engines or spark arresters who wish to have these equipments tested.

The arrester is tested on the engine it is specially designed for (as in this instance), or if it is sold for use on any or several engines, it is tested on an engine of the highest power for which the spark arrester is intended.

Automatic Waterers For Day Old Chickens, P Smetana, W. Ward

Journal of the Department of Agriculture, Western Australia, Series 4

ONE of the most tedious and time consuming tasks on a poultry farm is the provision of water to chicks from day old up to the age of three or four weeks.

Most poultry farmers use half-gallon glass fonts with metal bases for the first few weeks, until the chicks are old enough to use the automatic watering system usually situated along one wall of the brooder house.

This cumbersome glass font system can be replaced by the cheap and easily installed automatic watering system described below. This system has already been adopted by several local poultry farmers.

Getting The Best From Your Sewing Machine, O. Evans Scott

Journal of the Department of Agriculture, Western Australia, Series 4

"NEXT to the plough, this is perhaps humanity's most blessed instrument." (Louis Antoine Godey.)

In some homes the sewing machine is the most sadly neglected and ill-used servant. It is often left set up, exposed to dust, dampness and scratching, used as a table and otherwise abused.

It is not right to have a machine stitching imperfectly and noisily and used for long periods without maintenance when a little attention can keep it performing quietly and efficiently.

Temperature Distribution In An Infinite Plate As A Function Of The Input Heat Flux, George Franklin Wright

Masters Theses

"It is the purpose of this thesis to investigate the effects of a variable input heat flux impinging equally on both sides, on the temperature distribution within an infinite plate. An infinite plate may be defined as one in which the dimensions are infinite in two directions and finite in thickness. For practical purposes such a plate could be thought of as one in which the thickness was small enough, compared to the other two dimensions, so that a temperature gradient exists only normal to the surfaces of the plate. This assumption will be made to establish one-dimensional heat flow …

Transpiration Cooling Of A Plane Porous Plate, Raymond George Posgay

Masters Theses

"The transient temperatures were determined in a porous plate for one dimensional heat flow and one dimensional counter coolant flow. One surface of the porous plate was heated by a hot gas by convective heat transfer. A general discussion of the problem is considered and the procedure described for working all such problems dealing with transpiration cooling.

The solution of such problems is illustrated by two examples employing a ceramic plate one inch thick and cooled by a uniform flow of air in a direction counter to the flow of heat, while one surface of the ceramic plate was heated …
