Applications of Rayleigh Scattering to Turbulent Flows with Heat Transfer and Combustion.

Abstract

Rayleigh scattering has been developed as a diagnostic technique and used in conjunction with Laser Doppler Anemometry to study two reacting flows; the interaction of a Karman vortex street with a flame, and the interaction of grid-produced turbulence with a flame. It was found that one of the dominant effects of heat release and flow dilatation is to decrease turbulent kinetic energy, and to increase the integral scales of the turbulence. Flame holder drag is found to have a major effect on the flow-field behind the flame. The Markstein model for the effect of wrinkling on flame stability appears to be in qualitative agreement with the results of the vortex interaction experiments. (Author)
