AbstractIn this paper we describe our development of the LII technique for point measurement in flames and the calibration of the technique using a simple laminar diffusion flame. Since LII provides only relative soot volume fraction measurements, an absolute calibration is necessary. The radial soot volume fraction profiles in the laminar diffusion flame were measured by Abel inversion of line-of-sight attenuation measurements at 532 and 1064 nm. We have implemented a numerical model of the LII processes to aid in the interpretation of experimental results. A description of the LII technique and its calibration are discussed. The application of LII to a confined C3H8/air diffusion flame and some results of the model predictions and their comparison to experiment will be included in the presentation.
