cantly reduced. This suggests that a mechanism
other than the thermal mechanism played a signi cant role in NO production

under these conditions. Previous studies with other fuels have highlighted the
increased contribution of the prompt mechanism of NO x formation at

high equivalence ratios in partially premixed fl flames (Xue and Aggarwal 2003 ;

Briones et al. 2007 ; Love et al. 2011 ).
4. The overall soot content in the PME fl flames was lower than that of the Jet A fl ames.

The differences in temperature pro les in the two fl flames suggest differences in the

soot particle size and morphology.
