Raman scattering at 532 and 355 nm in atmospheric pressure propane/air flames, with and without liquid fuels

Abstract
We discuss an experimental investigation of Raman scattering spectroscopy in the vicinity of a simulated reacting liquid fuel spray. Spray flames are known to produce interference from droplet elastic scattering, laser-induced fluorescence, and laser-induced incandescence of soot. The goal in this work is to evaluate various experimental approaches to this challenging problem. We evaluate Raman scattering from both 532 and 355 nm beams (second and third harmonics of Nd : YAG), at various polarization orientations and over various lifetimes. We discuss tradeoffs between the various approaches and identify operating regimes in which such Raman measurements are possible. Perhaps the most compelling finding of this work is that the third...

We discuss an experimental investigation of Raman scattering spectroscopy in the vicinity of a simulated reacting liquid fuel spray. Spray flames are known to produce interference from droplet elastic scattering, laser-induced fluorescence, and laser-induced incandescence of soot.

We evaluate Raman scattering from both 532 and 355 nm beams (second and third harmonics of Nd : YAG), at various polarization orientations and over various lifetimes. We discuss tradeoffs between the various approaches and identify operating regimes in which such Raman measurements are possible. Perhaps the most compelling finding of this work is that the third harmonic of Nd : YAG holds more promise for measurement in high-pressure, combusting spray environments than has been previously thought.
