Abstract

fetched live from OpenAlex

In this paper, we illustrate two mechanisms of soot formation including the one in premixed ethylene flames and the other on in coal combustion in order to make a detailed review on soot formation. In the former one, the formation of high molecular weight aromatic species in premixed flames are explored by a detailed chemical kinetic mechanism. Key sequences of reactions in the formation of aromatics are the addition of acetylene to smaller aromatics, activated by H\|atom abstraction and the combination of resonantly stabilized radicals, including cyclopentadienyl radical combination, propargyl addition to benzyl radicals and the sequential addition of propargyl radicals to aromatic rings. So the HACA (H\|abstraction acetylene addition) model is built. And further research on resonantly stabilized radicals leads to the full modeling of the combination of HACA model and resonantly stabilized radicals. As to coal combustion, the processes are so complex that rare theses about it are found. It is commonly known that char and volatiles are produced after coal combustion and pyrolysis. Volatiles can form primary soot, then soot agglomerates are generated after primary soot agglomeration.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
