6 Summary and Conclusions

In summary, the global and in- fl ame combustion characteristics of pre-vaporized

and partially premixed flames of Jet A and PME were studied at initial equivalence

ratios of 2, 3, and 7. Based on the results obtained from measurements, the fol-
lowing conclusions were drawn:

fl

1. The global CO emission index was lower in the PME fl flames than in the Jet A

fl cant oxygen content in PME. The global NO emission

index in the Jet A and P100

flames due to the signi

flames was comparable at the equivalence ratios of
3 and 7, whereas the global NO emission index of Jet A

fl

fl flame was higher than

flames at the equivalence ratio of 2.
2. The radiative fraction of heat release of the P100

that of P100 fl

fl flame was lower than that of

the Jet A flame at the equivalence ratio of 7, whereas the values were compa-

rable at equivalence ratios of 2 and 3. This behavior was due to the increased
concentration of radiating gases and the reduction of soot content in the PME
