Fully Soot sheet characterization in a Vertical Wall-Flame by Laser Induced Incandescence (LII) Fully Soot sheet characterization in a Vertical Wall-Flame by Laser Induced Incandescence (LII)

Abstract : The aim of this work is to investigate the 2D slices though 3D soot-sheet into a turbulent non-premixed vertical-wall flame by using LII technique. Two studies are presented: A fully geometrical analysis and a velocity estimation of 2D soot-sheet. For the geometrical analysis, 2D spatially-resolved Laser Induced Incandescence (LII) has been performed. The surface, perimeter and major axis length of 2D soot-sheet have been determined. Evolution of soot-sheet dimensions within the height and the width in the flame are presented. It was found soot-sheet size and number increase within the height in the flame. For soot-sheet velocity, work is actually in progress about a new velocimetry methodology (Soot-Sheet Tracking Velocimetry). Principe, methodology and first results are presented.
