Abstract
Two dimensional shear flows of water, oil and oil-fibre suspensions of 0.01%, 0.025% and 0.05% mass consistency were examined using particle image velocimetry (PIV). A square obstacle that block 50% of the flow area in a rectangular flow cell induced shear. PIV measurements were taken at various positions on the plane of symmetry, adjacent to the square and in the wake region. The data shows that the higher viscosity of the oil results in a much larger boundary layer thickness than that of water and reattachment to the square that does not occur with water. The data also indicates that fibre loading causes a reduction in the intensity of vorticity and velocity fluctuations at the fibre length scale.

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; both teacher heads agree on what is shown here.
