Abstract
The performance of a coaxial mixer combining an anchor and a Rushton turbine was investigated for different diameter ratios and rotating modes in the laminar and transition flow regimes. Based on mixing efficiency criteria, this study confirmed that the co-rotating mode is consistently yielding the best results in the laminar and early transition regimes. The best performance was obtained for a turbine to tank diameter ratio of 1/3. In the upper transition and turbulent regimes, the best performance was obtained with the anchor at rest acting like two opposed baffles. With such a configuration, the optimum diameter ratio was found to be 1/2. New definitions of Reynolds number and power number were also introduced based on new characteristic diameter and speed. These correlations shown to be applicable for radial and axial impellers and are significantly better than the ones proposed in the literature.

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
