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.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
