Abstract: Several applications of laser diagnostic techniques to visualize
combustion phenomena are presented, including reactive Mie scattering for flow,
Rayleigh and Raman spectroscopy for major species, laser-induced fluorescence
for minor species, and laser extinction, scattering, and laser-induced
incandescence for soot. These techniques have been applied to diffusion flame
oscillation, a recirculation zone in a burner, laminar and turbulent lifted
flames, flame propagation along a vortex tube, and soot zone characteristics,
to demonstrate the usefulness of the techniques to provide a better
understanding of physical mechanisms.
