The relationship between burning rate, visible flame
length, and sooting properties of spray flames is
investigated. Multiwavelength emission/absorption
spectroscopy was applied to the measurement of soot
volume fractions and temperatures for high liquid
loading effervescent atomized flames. The statistics of
the emission and absorption data were interpreted in
terms of the statistics of the local properties using a
novel discrete probability function based deconvolution
method. The results show the coupled effects of soot
volume fractions and temperature on the radiative heat
loss from the spray flames. The effervescent atomized
burner configuration allows a study of the radiation
properties over a wider range of soot and temperature
combinations than that allowed by gas jet flames.
Comparison between conventional deconvolution techniques
and the present method show that consideration of
turbulence/radiation interactions is essential in
applying tomography to time varying fields.
