Abstract

fetched live from OpenAlex

Abstract Quantitative method is used to experimentally measure the minimum spouting velocity in shallow conical spouted bed. And a new minimum spouting correlation for shallow conical spouted beds is developed. It is based on spherical ZrO2 particles whose density is as high as 5890 kg/m3 while the other Ums correlations published so far are mainly based on relatively deep conical beds composed of lower density particles with density around or lower than 3000 kg/m3. The new Ums correlation can predict Ums of heavy particles well within the range of the experimental matrix. © 2011 Canadian Society for Chemical Engineering

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
