Abstract
Volumetric mass transfer coefficient, kLa, bubble size, and interfacial area were investigated in an aerated coaxial mixing system with an aspect ratio of 1.25 furnished with two central impellers and an anchor. The simplified dynamic pressure method and a combination of the dynamic gas disengagement and electrical resistance tomography methods were utilized for measuring kLa and bubble sizes, respectively. Carboxymethyl cellulose (CMC) solutions were used as the power-law non-Newtonian fluids. New correlations for the prediction of kLa in aerated coaxial mixing systems containing non-Newtonian solutions were developed. The pitched blade impeller in downward pumping generated the highest mass transfer and interfacial area and smaller bubble sizes at all anchor speeds and concentrations of the CMC solution. The anchor speed had a positive impact on the oxygen mass transfer up to 20 rpm. Bubble stability increased while the interfacial area decreased with an increase in the fluid apparent viscosity.

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
