Abstract : Soot measurements in laminar and turbulent diffusion flames are reviewed. In laminar flames, soot particles have high formation rates near the reaction zone and growth takes place in the fuel rich interior. Optical methods have revealed the regions of these separate processes with good spatial resolution. Sampling and optical techniques have been applied to turbulent flames to determine parametric influences upon soot formation and burnout rates. Recent experimental evidence indicates that formation rates can be mixing or chemically controlled. Burnout rates are additionally very influenced by temperature. Under simple conditions the smoking propensity of a flame may be determined only by the temperature near the tip. (Author)
