Abstract
An investigation of a flat plate with the liner-type (cavities covered by mesh) trailing-edge treatment is addressed in the present study to understand the influence of the geometrical parameters such as the cavity depth and the wire-mesh cell size on the noise generation mechanism. Previously, this noise control method showed high effectiveness during the test with a Controlled-Diffusion airfoil. The directivity measurements distinguish one configuration with shallow cavity and coarse wire-mesh which have the best noise performance. However, this configuration produces more noise at high frequencies than the configuration without mesh, due to the amplification of the cavity noise. The analysis of a Particle Image Velocimetry results along the treated area shows an increase of the boundary layer thickness and root-mean-square velocity fluctuations due to the liner-type treatment. The penetration of the flow into the treatment has been evidenced as well.

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
