Abstract
Atomizer is the key component of spray forming. In order to investigate the impact of the structure parameters on the atomization performance, the computational fluid dynamics method was applied to study the flow characteristic(including gas velocity V and aspiration pressure ΔP) of a Laval-type supersonic atomizer at different Laval nozzle throat structures, delivery tube tip angles and protrusion distances. Results show that in the three designed throat shapes such as: sharp-corner, smooth-corner and flat-corner, the comprehensive propulsion performance of the nozzle with smooth-corner throat is the best. For the studied atomizer, smaller delivery tube tip angle β can reduce the aspiration pressure, but speed attenuation increases, and the atomizer with a protrusion distance h ranging 7~8 mm has better aerodynamic effect. For the smooth-corner Laval shape, β=45° and h=8 mm are chosen for the atomizer used in the experiment, and rounded 7055 alloy powders with mass median diameter d50=42.3 μm are obtained by spray atomization progress at the atomization pressure of 0.8 MPa.

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.
