Abstract
Triple flames are of great importance in not only fundamental combustion research, but also industry applications. Since the triple flame phenomenon was first observed experimentally by Phillips in 1965, a number of theoretical and experimental studies have been devoted to the structures and propagation of triple flames from various viewpoints. However fewer studies have dealt with NOx emission characteristics of triple flames.... The purpose of the present paper is to investigate the NO, the dominant component of NOx, emission characteristics in triple flames by numerical simulation. To simplify the computations, the study was carried out for counterflow methane-air triple flames. The choice of methane as a fuel is because relatively detailed and complete chemical kinetics is available. The structure and NO emission mechanism in counterflow methane-air triple flames are discussed and compared to those of other corresponding counterflow premixed flames.

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 it
