This suggests that nearly zero soot formation occurs for this condition, since soot luminosity is typically orders of magnitude stronger than chemiluminescence emission .
no soot luminosity, as discussed in the next section), the combustion rate is likely dominated by chemical kinetics.
There are also fuel-rich regions near the bowl wall, as indicated by the bright soot luminosity.
While there are still bright pockets of soot luminosity, as noted previously, the majority of projected area is dominated by reactivity-controlled combustion.
Even by the image at 367 [degrees]CA, soot luminosity remains, although the AHRR is nearly zero, and thus in this case, soot burnout is not contributing significantly to sensible energy heat release.
Increased soot luminosity is correlated with a change in the AHRR profile as the peak AHRR rate precedes CA50.
