—Measurements of a conserved scalar have been made in a horizontal, hydrogen turbulent diffusion flame burning in a co-flowing stream of air. Laser light scattered by refractory seeding particles was a measure of the fuel element mass fraction (the mixture fraction). Present values of the mean mixture fraction agree well with those obtained by probe-sampling. Results have been presented both as conventional statistics and as Favre or density-weighted statistics. Probability density functions of the mixture fraction are near Gaussian on the centre-line and are strongly skewed on the edge of the shear flow. Conversion to temperature probability density functions yielded results which were in qualitative agreement with those obtained by other techniques. These probability density functions revealed a widely-spread instantaneous reaction zone throughout the flame with combustion being indicated on the centre-line close to the nozzle. Spectra of the scalar fluctuations were also obtained. |
