• Ethylene and acetylene jet diffusion flames have been studied by two photoelectron correlation techniques. One is laser Doppler anemometry used for determining the local average velocity, turbulence intensity, and velocity probability density. To obtain these, Fourier transform has been performed using the maximum entropy method. The other is the intensity fluctuation spectroscopy of a light scattered form soot clouds. Correlation signals, indicative of spatial distribution of soot-containing eddies, are processed to give the intergral scale of the eddies and the spectral density of the scattered-light. As the result, it has been suggested that in the flames tested, turbulence is intensified by a heat-release due to combustion and this augments the eddy structure of the jet, thus enhancing engulfment of the surrounding air and promoting its penetration into the jet core. A discussion is given of the effect of fuel on the size of the turbulent eddy.
