Étude théorique de la modélisation du rayonnement d’un plasma thermique : application à l’arc libre
Bibliographic record
Abstract
Le rayonnement est un aspect important de la physique des plasmas thermiques, notamment dans sa modélisation. Dans ces travaux seront présentées les méthodes couramment utilisées pour la modélisation du rayonnement des plasmas thermiques. On rappelle et décrit assez précisément les étapes de calculs qui aboutissent aux équations utilisées pour simuler le transfert radiatif dans les logiciels de modélisation COMSOL Multiphysics et ANSYS Fluent. A titre d’exemples et donc sans détailler l’implémentation de ces méthodes dans les deux logiciels, nous présentons, en fin d’étude, des résultats sur un arc libre d’argon à 200A afin de comparer les différentes méthodes entre elles et ainsi montrer leur impact sur la physique de l’arc

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.
