Constrained Inverse Fluidization of Light Particles in a Draft Tube Airlift Reactor
Bibliographic record
Abstract
The objective of this work was to investigate the main fluidodynamic behavior of a constrained inverse fluidized bed in a draft tube airlift reactor (DT-ALR), with liquid in batch and air in continuous mode. The inverse fluidized bed was formed of relatively large particles (4.3−5.4 mm) that were composed of light polyethylene (PE), in the first case, and of particles (3.7−4.7 mm) that were composed of extremely light polystyrene (PS), in the second case. The influence of physical properties of liquid phase (surface tension and viscosity) on basic fluidodynamic characteristics was examined using the coalescence-inhibiting medium (1 wt % aqueous solution of ethanol) and viscous medium (46 wt % aqueous solution of sucrose). It is shown that the overall gas holdup, induced liquid velocity, minimum fluidization velocity, and bed expansion are dependent on the superficial gas velocity and liquid and solid properties.

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.
