Abstract

fetched live from OpenAlex

Gas hold up was measured in mechanically agitated vessels fitted with dual impellers. Different impellers like Pitched blade turbine and Disc turbine were used. 5 different combinations of dual impellers were used. A tank of 0.45 m internal diameter with an impeller diameter of 0.15m was used. Superficial gas velocity was varied from 0.005m/sec to 0.01 m/ sec. Correlations are proposed for gas hold ups for different combinations of impellers. Optimum combination of dual impellers for maximum gas hold up has been identified. The effect of bottom clearance, inter impeller clearance and physical properties like surface tension on gas hold up were also studied for the optimum combination of impellers

Full frame distilled prediction

Teacher imitation

Not 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.
