LASER-INDUCED INCANDESCENCE AS A DIAGNOSTIC FOR SOOT PARTICULATE MEASUREMENTS

摘要

Laser-induced incandescence has emerged as a promising non invasive technique for measuring spatially and temporally resolved soot volume fraction and size. In this investigation we try to more assess its performance by characterizing particle size measurements using time-resolved LII. The experiments were performed in a premixed ethylene/air flame burning on a sintered stainless steel plug (McKenna) burner with different values of the equivalence ratio. The obtained results are in good agreement with the values measured by others techniques. The data analyzed with the help of validated LII models will be useful for the further development of soot formation models.
