Abstract
Hydropower is a renewable energy source with a lot of potential in Southeast Asian countries, with a total energy potential of 152,257 MW in Southeast Asia.The development of a hydro-turbine design is required due to the enormous hydropower potential.The turbine's runner is critical for converting fluid internal energy into kinetic energy.A cross-flow turbine that has gained popularity recently is the banki-turbine.The research that has been done is three-dimensional modeling of the banki-turbine with the CFD method.This study aims to determine the effect of the blade's angle on turbine performance.This research's steps are design, mesh independence, validation, simulation, and analysis.Modeling research was conducted with variations of blade angles 10˚, 15˚, and 20˚.Schematic modeling using a steady state condition, the turbulent type Shear Stress transport (SST), and the tetrahedral mesh method.The modeling consists of a rotating zone and a stationary zone.The water inlet velocity is 3 m/s, and the outlet pressure equals the room pressure (1 atm).Simulation of bankiturbine operated in 50 RPM until 350 RPM of angular velocity.One of the analyzes used is Factorial Design.The best performance Cpmax is obtained from the variation of the blade's angle of 15˚ on 0.28.

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
