Abstract
Mixing time experiments were performed using a coaxial mixing system consisting of an anchor impeller and three different types of impellers, namely a Rushton turbine, a Rayneri−Sevin impeller, and a new hybrid dispersing impeller. Both co- and counterrotating modes were investigated with Newtonian and shear-thinning fluids. It was found that mixing times were significantly reduced in corotating mode compared to the counterrotating mode or with the only impeller rotating at the same power per unit volume in the transition regimes. Among the various turbine impellers considered, the Rushton turbine was found to be the most effective one in terms of homogenization with Newtonian and non-Newtonian fluids.

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
