Shipboard observations of mean and turbulent atmospheric surface layer quantities SCCCAMP data report, Part I
(Monterey, CA; Naval Postgraduate School, 1986-05) Skupniewicz, C. E.; Borrmann, S.; Fellbaum, C.; Shaw, William J.; Vaucher, Christopher A.; Vaucher, Gail M. Tirrell; Physics (PH); Graduate School of Operational and Information Sciences (GSOIS); Naval Postgraduate School (U.S.); Dept. of Physics
3 Weeks of aerometric observations from a shipboard platform are described and analyzed to obtain surface layer quantities relevant to the dispersion of pollutants from offshore oil operations. Momentum, heat, and moisture flux were estimated with two different methods: the dissipation technique and bulk parameterizations. Diffusion scale turbulence was measured with bivane anemometers and estimates of ship motion contributions to these measurements were performed. Keywords: Turbulence diffusion; Measurements; and Santa Barbara Channel. (Author)

A perturbation theory for light diffraction from a bigrating with multiple surface-polariton excitation
(Monterey, CA; Naval Postgraduate School, 1986-12) Glass, Nathaniel E.; Physics (PH); Graduate School of Operational and Information Sciences (GSOIS); Naval Postgraduate School (U.S.); Dept. of Physics
A perturbation theory has recently been developed for treating the diffration of light, with surface polariton resonant excitation, from a bigrating surface. The theory is an approximation, to first order in the grating height, of an earlier theory based on the Rayleigh hypothesis. The perturbation theory holds for arbitrary polarization and for arbitrary plane of incidence with respect to the grating directions. It is, however, limited to treating only the possibility of two simultaneous resonant evanescent waves, whereas four are possible at normal incidence on a square grating, and three are possible on a rectangular grating. The present work generalizes the earlier work to allow for a four fold (or three fold) resonance. This extension also allows one now to determine the complex dispersion relation for surface-polaritons, for wavevectors at the intersection of two Brillouin zone boundary lines (not possible in the previous formulation).

Internal explosions of reactive aluminum with a PBX in air
(Monterey, California. Naval Postgraduate School, 1983-08) Reinhardt, Richard Alan; Physics (PH); Graduate School of Operational and Information Sciences (GSOIS); Dept. of Physics
Computations were performed for pressure, temperature and equilibrium product yield in the internal explosions of 208.5 lbs of reactive aluminum with 52.1 lbs of a PBX in air for air volumes ranging from 2000 to 50000 cubic feet. The decrease in overpressure with increasing volume is interrupted by a temporary rise in the region where the solid present changes from A1N to A1
