Experimental investigation on pressure drop of a laboratory‐scale random packing column under roll and heave motion
Bibliographic record
Abstract
Abstract The effects of tilt, roll, and heave ship motion on pressure drop were investigated in a laboratory‐scale random packing, which was located at a six degree of freedom (6DoF) motion parallel platform. The water‐air system was adopted, and various operating condition (liquid load and F‐factor) as well as sea states were tested. In tilted states, the pressure drop was decreased as the tilted angle increased, which was associated with the reduction in liquid hold‐up. Under a roll and heave motion, it was found that the pressure drop fluctuated around the value of vertical state. Subsequently, the relative change in pressure drop was introduced to reflect the influence of sea state. It was found that the relative change in pressure drop monotonously decreased as the heave motion frequency decreased, but it could inversely increase under a low‐frequency roll motion, particularly under high liquid load with a large size Pall ring.

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.
