Abstract
Based on the Cluster renewal Model of the particle motion in a CFB riser, the authors developed a revised heat transfer model, which introduced the latest research results of the hydrodynamics of the suspension flow in CFB. This model divided the heat transfer into two parts, which are due to the transient heat conduction by the covered clusters and the convection between the uncovered wall and the dispersed phase. Radiation at high temperature was regarded as being additive. The fraction of the covered wall by clusters and the thichness of the gas gap between clusters and wall were revised by a new formula, which is a function of the operating condition and the particle properties. The radiation between the dispersed phase and the uncovered wall included not only the direct radiation to the uncovered wall, but also the radiation to the clusters and then reflected to the uncovered wall. The model results showed good agreement with the published experimental data, which proved the modification was reasonable. Figs 4, table 1 and refs 10.

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
