Abstract
Abstract Experiments and simulations of a solids suspension process in a lab‐scale stirred tank under turbulent conditions have been performed. Two impellers have been tested. The liquid‐solid suspension consists of water and a mixture of glass and bronze particles. The simulations are Eulerian‐Lagrangian with the liquid flow as the Eulerian part, being solved by means of a lattice‐Boltzmann method combined with a large‐eddy approach to turbulence modeling. Comparison with experimental visualizations indicates that the simulations are able to represent the start‐up of the suspension process from a zero‐velocity initial condition. Differences between experiment and simulation are observed near the bottom of the tank. The simulation data are used to highlight the collisional interaction between the two different types of solids, the role of baffles, and the effect of impeller type on the suspension process.

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
