The combustion mechanism of aluminium in the steam/carbon dioxide mixed atmosphere
Bibliographic record
Abstract
Abstract The ignition and combustion characteristics of aluminium (Al) in the steam/carbon dioxide (H 2 O/CO 2 ) mixed atmosphere were calculated by using a close homogeneous catch reactor and premixed laminar flame‐speed of CHEMKIN‐PRO. The effects of initial reaction temperature and H 2 O/CO 2 ratios on the system temperature, products, and ignition delay time were explored. The main reaction paths were analyzed by the temperature sensitivity. Al (l) entered the system with a pronounced phase transition and only one heating stage, but there are two heating stages in the Al (g) system. The reaction of Al in the H 2 O/CO 2 mixed atmosphere has a positive effect on the ignition delay time of the system. The high contents of CO 2 in the H 2 O/CO 2 mixed atmosphere can increase the maximum temperature of system and decrease the ignition delay time. Temperature sensitivity analysis shows that AlO, Al 2 O, and AlOH are important intermediate products, and Al 2 O 2 is the main substance that produces Al 2 O 3 . The dominant reaction path is Al → AlOH→AlO → Al 2 O → Al 2 O 2 → Al 2 O 3 . In addition, when the initial temperature was 2300 K, the laminar flame velocity was calculated to reach 35.6 m/s.

How this classification was reachedexpand
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.
