Design of nozzles for partly ionized gases
An analytic expression is obtained for the speed of sound in a partly ionized gas under certain conditions. The method of characteristics is adapted to use this information for the solution of the compressible gas flow ...
A two dimensional photoelastic study of the load distribution among the roller bearings in a rock bit
The photoelastic technique was employed to investigate the adverse affect on the load distribution among the roller bearings in a rock bit cutter as a result of the relatively large radial clearance in the bearings. A ...
An experimental and analytical investigation of the effect of tray liquid on the vibration behavior of bubble towers
Study of field observations indicates that tray liquid affects the vibration behavior of a bubble tower as would a tuned dynamic vibration absorber. In this thesis an analytical investigation and experimental model studies ...
Electron emission from aluminum as a result of plastic strain
Aluminum was strained in tension under a Geiger counter. Electron emission associated with plastic deformation and subsequent delayed emission was observed. The specimens were illuminated during both the growth and decay ...
Primary creep of polycrystalline copper and determination of the activation volume
Creep experiments were conducted using high-purity polycrystalline copper at 78°K and 300°K. The results arc analyzed in terms of an intersection mechanism between the moving and forest dislocations. The activation volume ...
The design of a model for studying vibrations in rotary drilling strings
Dimensional analysis methods are used in designing a model rotary drilling string on which vibrational studies may be made. Practical considerations and limitations of materials necessitate making various approximations, ...
