Abstract
Gas atomization can be used in producing high-quality metal powder and the atomizer has great influence on the production quality. In this paper, the annular orifice atomizer is optimized by adopting Laval nozzle as the shape of gas jet orifice and a three-dimensional model of supersonic annular orifice atomizer is adopted to investigate the flow field characteristic at different atomization gas pressure (P <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</sub> ), including gas velocity, static pressure and aspiration pressure at the delivery tube tip. The numerical results indicate that the maximum gas velocity in the atomization zone increases with increasing P <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</sub> . The aspiration pressure is also found to increase as P <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</sub> increases. Comparing with annular slit atomizer, there is no airflow shock wave in the flow field, which can weak the atomization effect.

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.
