Abstract
The properties of the pressure drop in a medium-aspect-ratio vortex chamber with double outlets are examined both experimentally and theoretically. Dimensional analysis provides the functional relationships between the main dimensionless groups. Application of the integral equations of continuity and energy over the control volume, along with the minimum-pressure-drop principle, furnish the required formulas that relate the predominant nondimensionalparameters. In the vortex-dominatedregime, the theoretical results, given in terms of the pressure drop across the chamber, are found to agree with the experimental observations. The larger outlet has been shown to control the ow. A considerable reduction in static pressure drop across the chamber can be gained by adding an extra outlet at the opposite end-plate.

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
