Explosion Characteristics of Syngas/air Premixed Flames
Bibliographic record
Abstract
Explosion of a fuel/air combustible mixture in a closed system has been recognized as a serious hazard, because it may damage a chamber if there is no proper venting or explosion suppressing device. In the present study, important explosion characteristics of syngas/air flames were investigated in order to evaluate the hazard of the combustion. Results showed the maximum explosion pressure increased from lean (equivalence ratio of 0.8) to an equivalence ratio, of 1.2, then decreased significantly with richer mixtures, indicating that maximum explosion pressure occurred at = 1.2, while explosion time was shortest at = 1.6. Increasing hydrogen content in the fuel blends significantly raised laminar burning velocity and shortened the explosion time, thereby increasing the maximum rate of pressure rise and deflagration index. Normalized peak pressure, the maximum rate of pressure rise and the deflagration index were sensitive to the initial pressure of the mixture, showing that they increased significantly with increased initial pressure.

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.
