Interactions of spout jets in a multiple‐spouted bed
Bibliographic record
Abstract
A three‐dimensional (3D) computational fluid dynamics (CFD) model, coupling with two‐fluid model (TFM) approach is adopted to investigate the interactions of spout jets and to evaluate the effects of baffles in a multiple‐spouted bed. For two typical flow patterns, that is single spouting and double‐spouting, characteristics of flow patterns, solid velocity and voidage are investigated with varying spouting gas flow rates. Influence of baffles set in the bottom of the bed is also studied in three typical flow patterns. Results show that for double‐spouting, the central spouting push off the lateral spouts, and the push force is increasingly obvious with increasing central spouting gas flow rate; for single spouting, when the lateral spouting gas flow rates increase, the central spout is destroyed and the gas‐solid flow becomes unstable. Baffles in different flow patterns (single spouting, double‐spouting and triple‐spouting) exert different effects on the solid movements.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
