Abstract
are discussed. Significant differences are observed in the reconstructed Reynolds stress profiles at the center of the separated shear layer and those close to the reattachment point. The results also indicate that contribution of the energetic structures to the Reynolds stresses is higher at the upstream section of the ribs than in the separated layer. Thiswasattributedtoamoreuniformenergydistributionamongtheproperorthogonaldecompositionmodesinthe separated shear layer than in the upstream section. The distributions of the mean velocity, mixing length, and eddy viscosityatselectedlocationswerealsoanalyzed.Themixing-lengthprofilesintheinnerregionoftheseparatedshear layer do not follow the well-documented linear profile reported for simple near-wall turbulent flows.

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
