The effect of cell geometrical design and hydrodynamic conditions on the gas dispersion of Jameson cell
Bibliographic record
Abstract
Des décennies de développement ont permis à la Jameson Cell de devenir un dispositif de flottaison populaire dans les domaines du charbon, du traitement des métaux de base et d'autres applications spécialisées. Néanmoins, sa vigoureuse production de bulles et ses mécanismes de mélange bulles-boue ne sont pas encore entièrement compris. Par l'utilisation de capteurs et de techniques de visualisation de bulles les plus récentes, ce travail examine, de façon expérimentale, la façon dont la performance d'une Jameson Cell de laboratoire est reliée aux variables de conception et d'opération. Les résultats de ce travail contribuent au travail des opérateurs et des modeleurs de la Jameson Cell. Certains des résultats importants sont: la taille de l'orifice et la longueur du 'downcomer' ont un impact positif sur le vide dans le 'downcomer', cela favorise de petites bulles et la rétention de gaz haute, la pression de jet supérieur génère de petites bulles, la longueur du tuyau de descente n'a pas d'effet significatif sur la taille des bulles.

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.
