Experimental analysis of multi-horizontal submerged jets energy dissipater
Bibliographic record
Abstract
The use of a stilling basin with multiple horizontal submerged jets emerging from two layers has been suggested for use as an energy dissipation structure in hydropower stations. In this study, laboratory velocity measurement is performed to analyze the three-dimensional flow structure of submerged jets and to evaluate the effect of the downstream submergence on the flow field. The results indicate that the Reynolds shear stress and vorticity magnitudes increase with increasing jet submergence. Further, it was found that submergence increase leads to a decrease of 2.2% in maximum bed (floor) shear stress and 7.2% in side-walls shear stress. The Reynolds shear stress quadrant decomposition is also performed for all (H = 0) and high magnitude (H = 2) bursting events, which indicate that the turbulence events of outward and inward interactions made dominant contributions to the total Reynolds stress. Turbulent kinetic energy is also analysed to obtain a better characterization of the flow field.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
