Abstract
Abstract The aerodynamic performance of three different configurations of vertical axis wind turbines ( VAWT ), namely: (a) conventional Darrieus troposkein VAWT (based on turbines designed by Sandia National Laboratories), (b) novel 50% STS ‐ VAWT (50% shifted‐troposkein‐shaped STS ‐ VAWT ), and (c) novel 100% STS ‐ VAWT were investigated numerically. An in‐house code, which combined the blade element theory ( BET ) and the vortex filament method ( VFM ), was used. The main purpose of this work was to develop an aerodynamic code to predict the performance of conventional VAWT as well as assess the novel 50% and 100% STS ‐ VAWT configurations. Simulation results (power coefficients) were verified and then validated against experimental data available from the literature (2‐, 5‐, and 17‐m conventional troposkein VAWT measured by Sandia National Laboratories). Additional numerical results showed that the 50% STS ‐ VAWT outperformed both the conventional VAWT and the 100% STS ‐ VAWT by up to 14% (peak power), within the range of rotation and turbine sizes that were investigated in the present work.

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
