Experimental and theoretical comparison of spatially resolved laser-induced incandescence signals in a sooting flame
Författare
Summary, in English
A detailed experimental and theoretical investigation has been made on the use of Laser-Induced Incandescence
(LII) in two configurations; right-angle LII and backward LII. Both right-angle and backward LII imaging
measurements were conducted in simultaneous experiments at various pulse energies. The theoretically calculated LII signals were based on a heat transfer model for soot particles exposed to laser radiation, and were compared with the experimental LII images. Both the experimental and theoretical results from this initial comparison showed similar general behaviour, for example the broadening of the spatial LII distribution and the hole-burning effect at centre for increasing laser pulse energies.
