Propagation of a detonation in a converging conical channel
Bibliographic record
Abstract
The presented work is an experimental study of detonation propagation in a converging conical channel.We explore the amplification of the detonation wave in a conical tube with a small angle of convergence.Experiments were carried out in a detonation tube which has a straight, constant area cylindrical section with inner diameter of 6.35 cm and length of 3 m.At the end of the cylindrical tube is the conical tube.A Chapman-Jouguet (C-J) detonation wave is first established in the constant area portion of the tube prior to entering the converging section.Two explosive mixtures: stoichiometric acetylene-oxygen mixture (C 2 H 2 + 2.5O 2 ) and acetylene-oxygen mixture with 70% argon dilution (C 2 H 2 + 2.5O 2 + 70% Ar) were used.The initial pressure range of the experiments are from 0.5 kPa to 10 kPa and from 4 kPa to 16 kPa respectively for the two mixtures.

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.
