Variables in turbine erosion
Study of impact erosion in the operation of turbomachinery is undertaken to predict the results for particular designs. The test program investigates the effects of turbine stator blade shape, rotor blade shape, and variations in test conditions
Droplet monitoring probe
A droplet monitoring system is disclosed for analysis of mixed-phase fluid flow in development of gas turbines. The system uses a probe comprising two electrical wires spaced a known distance apart and connected at one end to means for establishing a dc potential between the wires. A drop in the fluid stream momentarily contacting both wires simultaneously causes and electrical signal which is amplified, detected and counted

Evidence for Braggoriton Excitations in Opal Photonic Crystals Infiltrated with Highly Polarizable Dyes
We studied angle-dependent reflectivity spectra of opal photonic crystals
infiltrated with cyanine dyes, which are highly polarizable media with very
large Rabi frequency. We show that when resonance conditions between the
exciton-polariton of the infiltrated dye and Bragg frequencies exist, then the
Bragg stop band decomposes into two reflectivity bands with a semi-transparent
spectral range in between that is due to light propagation inside the gap
caused by the existence of braggoriton excitations. These novel excitations
result from the interplay interaction between the Bragg gap with spatial
modulation origin and the polariton gap due to the excitons, and may lead to
optical communication traffic inside the gap of photonic crystals via channel
waveguiding.Comment: LaTex, 5 pages, 3 figures include
