Abstract
Potential flow methods are a promising alternative to mainstream wind turbine aerodynamics tools such as blade element momentum methods and grid-based computational fluid dynamics approaches. Potential flow methods are relatively easy to setup and robust with respect to geometry. The advent of the fast multipole method and viscous core modelling brings computational speed and robustness. A C++ library employing a Weissinger lifting line model and tailorable potential flow wake models has been developed under the name LibAero. The wake models employ vortex particles, vortex filaments, and vortex quadrilateral elements. Aerodynamic wake models were validated against experimental data from the MEXICO wind tunnel experiments in steady axial wind conditions. Blade forces and flow field data were compared. The experimental blade forces were post-processed from airfoil pressure tap data, whereas flow field data was post-processed from particle image velocimetry data. The results indicate that LibAero is effective at predicting blade forces, power, and thrust. LibAero is similarly effective to blade element momentum methods for modelling the aerodynamics of standard Danish wind rotors, while having the capability to model non-standard wind rotors.

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
