The effect of quenched-in vacancies upon the elastic modulus of aluminum ma investigated. Equipment for dynamically measuring the change in elastic modulus was developed for the purpose. It was demonstrated that the presence ...

The primary objective of this work was to experimentally determine the degree of ionization in a partially ionized gas flowing in a converging-diverging nozzle. Stagnation point Langmuir probes were employed for this ...

The author wishes to express his appreciation to Professor Paul R. Paslay for his suggestion of this thesis topic and for his invaluable assistance and advice during its preparation. Gratitude is also extended to my wife, ...

This work is concerned with the motion of a rigid sphere which is accelerated by an accelerating fluid inside a cylindrical tube where both the sphere and the fluid are initially at rest. The investigation is valid for ...

A Mach-Zehndcr interferometer using a helium-neon laser and a high speed closed-open-closed shutter was designed and constructed in the present plasma facility in the Department of. Mechanical and Aerospace Engineering and ...

A solution to the boundary layer equations for en incompressible fluid flow through a converging nozzle is presented. Calculations are based on a nozzle whose walls have a constant radius of curvature and a 2:1 entrance ...

An equation of motion governing lateral deflection, considering elastic, dynamic, and drag forces is derived. This equation is applied to three different classes of drill string behavior: a beam with constant axial tension, ...

The precipitation of the omega phase in quenched titanium-vanadium alloys of 15% to 25% vanadium was investigated by x-ray analysis and resistivity measurements. The omega phase precipitation was found to be controlled by ...

The analytical research accomplished, and reported herein, includes the development of a computerized analytical technique for evaluating certain aspects of the gas diffusion phenomena normally evident in spacecraft. This ...
