Analytical Investigation Of Thin And Moderately ThickWalled Tubing Under Peripheral And Biaxial Loading, Frank Joseph Cizek
Analytical Investigation Of Thin And Moderately ThickWalled Tubing Under Peripheral And Biaxial Loading, Frank Joseph Cizek
Masters Theses
"The problem then, resolves itself into a study of the behavior of thinwalled and moderately thickwalled cylinders under the effects of an external fluid pressure acting alone, or the effects of an external fluid pressure acting simultaneously with an axial loading. In this thesis a theoretical or analytical approach will be used. Some application and reference will be made to oilwell casings in particular, but the solutions will not be restricted to oilwell casing alone. it must be recognized that the tubing problem involves the problem of unstability before the proportional limit of the metal is exceeded and a similar ...
The Application Of The Relaxation Method To The Solution Of Problems Involving The Flow Of Fluids Through Porous Media, Alexander Antoine Zwierzchowski
The Application Of The Relaxation Method To The Solution Of Problems Involving The Flow Of Fluids Through Porous Media, Alexander Antoine Zwierzchowski
Masters Theses
"The purpose of this investigation is to determine the feasibility of applying the relaxation method of mathematical analysis to the solution of problems in rheology. The relaxation method was first introduced by R. V. Southwell who applied it to the problem of electrical conductivity. It was later used by M. W. Emmons to solve twodimensional heat conduction problems. The steadystate flow of fluids through porous media can be difficult or impossible by the usual analytical methods even with rather simple boundary conditions. The relaxation method promises to provide an easier method of solution and to provide a means of solving ...
Torque Characteristics Of High Speed Steel Twist Drills, Tien Chi Lee
Torque Characteristics Of High Speed Steel Twist Drills, Tien Chi Lee
Masters Theses
"The drill is the most efficient tool used by machinists, for in no other tool is the cutting surface as large in proportion to the cross sectional area of the body or part that is its real support. Drills have shared evolutionary developments from carbon steels to high speed steels and from flat to twist drills. Many investigations have been made on the twist drills, but due to the majority of their work being based on the size of drills from 1/2 to 11/2 inches or larger, there is a dearth of published data on the general problem ...
The Effect Of The Convection Coefficient On The Temperature Amplitude In Periodic Heat Flow, Gordon L. Scofield
The Effect Of The Convection Coefficient On The Temperature Amplitude In Periodic Heat Flow, Gordon L. Scofield
Masters Theses
"The problem to be investigated in this thesis is that of periodic heat flow in a semiinfinite solid. Periodic flow means that heat flow is a continuous function of time and repeats itself at regular intervals. A semiinfinite solid is one which is bounded by one and only one plane. This subject has received considerable attention in the field of soil temperatures, both at the surface of the earth and at various depths. The surface of the earth is subjected to temperature changes which are nearly periodic. These temperature changes take place both daily and annually. A knowledge of these ...
Automatic Wheel Balancer For Automobile Wheel, Frederick Eugene Nevin
Automatic Wheel Balancer For Automobile Wheel, Frederick Eugene Nevin
Masters Theses
"Automobiles of today have been so constructed that greater speeds under safer conditions now exist. One of the improvements has been the low pressure tire. These tires carrying less pressure necessitates a casing of greater volume. This has created a tire of greater thickness in the axial direction but at the same time has decreased the diameter. Because of these innovations in presentday tires the author believes the wheel assembly (tire, tube, wheel, and brake drum) should be considered as a rotating cylinder not as a rotating disk. This being the case, the condition of dynamic unbalance is more critical ...
The Application Of The Relaxation Method To The Solution Of Problems Involving The Flow Of Gases Through Porous Media, Ralph Davis
The Application Of The Relaxation Method To The Solution Of Problems Involving The Flow Of Gases Through Porous Media, Ralph Davis
Masters Theses
"The purpose of this investigation is to determine the feasibility of applying the relaxation method of mathematical analysis to the solution of problems involving the flow of gases through porous media. The relaxation method was first applied to twodimensional problems by Christopherson and Southwell, who applied it to problems in stress analysis. It was later applied to steadystate heat conduction problems by H. W. Emmons and to steadystate flow of incompressible liquids by A. A. Zwierschowski. The solutions of problems involving the flow of gases through porous media is difficult for all but the simplest boundary conditions, and impractical for ...
Water Injection In The Modern Automotive Spark Ignition Engine, Leonard Carl Nelson
Water Injection In The Modern Automotive Spark Ignition Engine, Leonard Carl Nelson
Masters Theses
"The injection of water in the spark ignition engine is not new. The effect of humidity in the air on the performance of the spark ignition engine probably initiated the early investigations. The water vapor in the inlet air decreases the speed of the flame front and necessitates spark advance to assure maximum power and maximum efficiency. Water particles in the air evaporate during the compression and combustion of the inducted charge and decrease the tendency of the engine to detonate. These effects are very evident when operating the spark ignition engine in a moist atmosphere. Water is not a ...
