The effect of compressibility on the Rayleigh-Taylor instability for a theta pinch plasma column, 1969
Item — Call number MU Thesis Reg
Identifier: b2088222
Abstract
Since the original work by [Sir Geoffrey Ingram] Taylor several authors have reported theoretical and experimental calculations on Rayleigh-Taylor and other gravitational instabilities for various fluid and field geometries of magnetohydrodynamical interest. In the particular case of the theta pinch geometry, a Rayleigh-Taylor instability is found to occur in the first (adiabatic) expansion stage of the columns, with experimental growth rates of the proper order of magnitude for this type...

The refractive index of thin silicon dioxide films deposited by using a CO₂ laser, 1973
Item — Call number MU Thesis Joh
Identifier: b2088650
Abstract
A CO₂ laser was employed as the heat source to deposit films of SiO₂. The report discusses the measurement of the refractive indices of the thin transparent films produced.
Investigation into the various techniques available for measuring the index of refraction led to the selection of Abeles method for determination of the Brewster angle. A helium-neon laser was used as the source of incident polarized light, while a selenium photocell monitored the reflected...

Viscous effects on the Rayleigh-Taylor instability, 1969
Item — Call number MU Thesis Com
Identifier: b2088193
Abstract
The gravitational instabilities of a system consisting of two homogenous fluids in concentric cylindrical configuration (theta-pinch), in the presence of a uniform axial magnetic field, are investigated. The fluids are assumed to be incompressible, and viscous, with infinite conductivity. The dispersion relation is developed by two methods. In the first, an exact determination is made based upon the time development of an infinitesimal disturbance of the equilibrium conditions. In the...
