Abstract
Abstract Turbulent flows in concentric and eccentric annuli with and without rotating inner cylinder were investigated by numerical simulations. Similar flows occur in drilling operations of oil wells. Several turbulence models with Reynolds Average Navier–Stokes approach were used in the simulations and the respective models predictions were compared with experimental data from the literature. The simulated results of axial and tangential velocities show a good agreement with the experimental data. As compared with another turbulence models, the simulations with the standard Reynolds Stress model presented a slightly better prediction for most of the responses studied.

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
