Abstract
The light scattering technique is used to measure the statistics of a conserved scalar in a hydrogen jet diffusion flame. Measurements of the means, root mean square fluctuations and probability density functions are made for flames at two Froude numbers. The results are presented as conventional and as Favre quantities. Conventional means are near sampled composition measurements but Favre means drop considerably faster on the centreline. The probability density functions reveal that in the buoyant turbulent flame the profiles are intermittent and far from Gaussian downstream. Favre rather than conventional probability density functions in the flames are found to resemble isothermal data.
