Abstract:

The Mechanical Engineering Department at Vanderbilt University obtained a high pulse energy Nd-YAG laser, together with a dye laser and frequency doublingmixing system. This laser system provides the light sources necessary for nonintrusive, unseeded velocimetry of low temperature air flows, with applications to base flows and high speed flows around projectiles. The laser system also provides high pulse energy light for visible Raman scattering measurements in rich, hydrocarbon-fueled flames. The visible wavelength and high pulse energy allow strong, interference-free Raman signals to be obtained in flame regions where fluorescence interference precludes application of the UV Raman scattering technique.
