Abstract
In the present paper both steady and unsteady CFD analysis were performed to investigate the flow behavior in a bulb turbine. A study was carried out to assess the effect of runner tip and hub gap size on the turbine performance. Also special attention was paid to the turbine power break off at full load condition as well as the hysteresis phenomena on the turbine efficiency curve occurring in the same region. The unsteady calculations were performed only for some operating points of interest near the power break off region. The numerical results were compared with experimental data from the BulbT project.

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
