Abstract
The effect of a nozzle's internal geometry on a water jet issuing into a subsonic cross airflow was studied experimentally to determine the jet's breakup length and trajectory. The geometrical parameters considered were the nozzle's diameter, nominal surface roughness, length-to-diameter ratio and contraction angle. Although the nozzles employed were not transparent, near-field photographs and column breakup lengths of a water jet discharged into a quiescent atmosphere (i.e., having no airflow) allowed conditions to be identified that promoted cavitation or hydraulic flip. Results revealed that a nozzle's geometry influenced the corresponding water jet's breakup length only at high momentum flux ratios. Furthermore, the trajectory of a water jet from a nozzle experiencing cavitation or hydraulic flip, when discharged into a subsonic crossflow, was found to be almost insensitive to the nozzle's geometry.

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
