Abstract
This work addresses the simulation of transitional flow over airfoils under low Reynolds number conditions (Rec � 60000). The flow solutions are obtained by means of an Implicit Large Eddy Simulation (ILES) using a newly developed unstructured, parallel solver that employs the high-order spectral difference (SD) method for spatial discretization. The calculations are performed on the SD7003 airfoil section at an angle of attack of 4 ◦ at Reynolds number of 10000 and 60000. The SD7003 airfoil was selected due to the availability of experimental and computational results. The use of the SD method without an added subgrid-scale model appears to be capable of accurately predicting the laminar separation, transition and reattachment locations. To the authors’s knowledge, the present study is the first att empt to analyze transitional flow using the SD method.

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
