Experimental methodology to characterise soot in Diesel flames combining different optical techniques

A complete methodology to obtain bi-dimensional soot volume fraction, number density and temperature in Diesel flame has been developed combining the Planar Laser-Induced Incandescence (PLII) technique with Laser Elastic Scattering (LES) and two-colour pyrometry.

Planar LII can provide two-dimensional distribution of soot volume fraction, but combined with LES techniques can provide also relative particle number and number density. The methodology presented includes guidelines for a proper use of the combined technique, together with calibration and signal correction procedures, and calculation software to convert the incandescence and attenuation signals into quantitative information about soot structure and development in Diesel flames. This information is combined with flame temperature obtained with two-dimensional two-colour pyrometry.
