Abstract
Abstract Simulations of solid–liquid flow in an agitated tank have been performed. The simulations fully resolve the mildly turbulent liquid flow (Re ≈ 2000) in the tank, and the spherical solid particles suspended in the liquid. Full resolution of the particles sets the grid spacing and thereby limits the tank size and the number of particles (up to 3600 in this article) that are computationally affordable. The solids volume fraction is some 8%. The lattice‐Boltzmann method has been used to solve the flow dynamics; the particles move under the influence of resolved hydrodynamic forces, unresolved lubrication forces, net gravity, and collisions (with other particles, the tank wall, and the impeller). We show the start‐up of the suspension process, demonstrate its dependency on a Shields number (that we interpret in terms of the Zwietering correlation) and show the impact of polydispersity on the suspension process. © 2012 American Institute of Chemical Engineers AIChE J, 58: 3266–3278, 2012

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
