A numerical study on NO formation in counterflow n-heptane triple flames
Bibliographic record
Abstract
Many studies have been devoted to the structures and propagation of triple flames. However, fewer studies on NOx formation in triple flames have been reported. It has been shown that NOx formation in a flame is closely related to the flame structure. Our recent study on NOx formation in methane/air triple flames showed that the mechanism of NOx formation in a triple flame is different from in either a premixed or a diffusion flame, due to the specific structure of a triple flame. n-Heptane is a relatively heavy hydrocarbon fuel that is generally used to simulate a diesel combustion. The purpose of the present paper is to numerically investigate NO, the dominant component of NOx, formation in n-heptane triple flames. The discussions first focus on the results for two typical triple flames that exhibit the most significant features of triple flames. Then the effects of the variation in the equivalence ratio of the lean or rich mixture and the stretch rate will be examined.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
