Abstract
Abstract Dust explosions are combustion of fine dust particles in a rapid reaction regime. They are of relatively common occurrence in industries which have unit operations like grinding, pneumatic conveying, drying, and fine particle collection: generally those units which handle fine particles or “dust” in an oxygen‐rich environment. At present, mitigation and prevention of dust explosion accidents is largely based on operator experience and safety inspection heuristics: knowledge that often cannot be documented or put into scientifically developed safety rules. Part reason for this state of affairs is our lack of fundamental understanding on how a dust explosion progresses after ignition of the dust cloud. In this contribution, with a view towards improving our understanding of dust explosions, we propose a multi‐scale modelling approach for modelling dust explosion phenomena in a standard 20 L Siwek Apparatus. The modelling approach is based on computational fluid dynamics methods treating Aluminum dust cloud as a quasi‐homogeneous phase.

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 it
