PAHs were formed within the main reaction zone and were rapidly destroyed, while soot was formed.
Downstream in the postcombustion gases, the peak scattering signal is several orders of magnitude larger than the peak value near the main reaction zone of the flame.
Quasi-steady NO concentrations measured in the jet core are compared to detailed kinetic simulations, taking the residence time of the fluid parcels in the main reaction zone into account.
In contrast, only about 10% of the CF4 is consumed in the main reaction zone and it reduces the burning velocity primarily by lowering the final temperature of the burned gases.
The resultant chemical structure at the main reaction zone can be explained by the local composition change of the gas flowing into the reaction zone from the preheat zone.
Although the main reaction zone appears to be broadened by its associated high turbulent intensity, a combination of statistical analysis plus flamelet simulations suggests that the primary internal structure responsible for the OH distribution remains constant across the mean flame brush.

Planar laser induced fluorescence (PLIF) of OH radical measurement is adopted to identify main reaction zones and burnt gas regions as well.
Measurements were made in the main reaction and post-reaction zones for a number of low molecular weight species, aliphatics, aromatics, and polycyclic aromatic hydrocarbons (PAHs) ranging from two to five-fused aromatic rings.
The main reactions in this zone were shown to be the oxidation of hydrogen and carbon monoxide produced within the inner zone.
The main reactions involved in the secondary reaction zone, including CO + OH⇔CO2 + H (R94), H + O2 + M⇔HO2 + M (R31), HO2 + OH⇔H2O + O2 (R82) and H2 + OH⇔H2O + H (R79), are related to accumulated intermediate species including CO, H2, H, and OH.
In order to avoid the undesirable effects of creviced piston, the crevice zone is separated from the main reaction chamber at the end of compression.
