Abstract
A numerical analysis of the flow near the nacelles of two wind turbines is performed through 3D RANS simulations with the k-ω sst turbulence model. The rotor is modeled using three approaches: two techniques based on the actuator disk and one based on the actuator line. The effects of the rotor representation on the predicted flow at the location of the nacelle anemometer are quantified. In general, agreement with measurements is better for the actuator line than the actuator disk which tends to underestimate the wind speed in the very near wake. At low wind speeds, the three rotor modelling techniques predict nearly identical nacelle transfer functions; differences appear at higher wind speed where the the actuator line is slightly better compared to the other techniques.

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
