Numerical investigation of ?ow structures development of the slat cove ofthe ?ow past a three-element high-lift wing
Bibliographic record
Abstract
Three-dimensional simulations of the ?ow past a 30P30N three-element high lift wing are performed at low Reynolds numbers O 104 using a high-order spectral element method. The study focuses on investigating ?ow structures of the slat cove and Go¨rtler vortices that appear on the top of the main airfoil. The spanwise velocity component is measured in the slat cove and shows a sinusoidal form with a ?xed wavelength corresponding to the later observed Go¨rtler vortices. The amplitude of the spanwise velocity grows exponentially in time for approximately 6 orders of magnitude before a saturation is observed. Proper Orthogonal Decomposition (POD) modes are next used to analyze the ?ow structures development of the slat cove for different time ranges. It is shown that the ?ow in the slat cove is ?rst dominated by shear layers which evolve into spanwise perturbations. These perturbations later develop into bell-shaped structures and ultimately form Go¨rtler vortices.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
