Abstract

fetched live from OpenAlex

In the present paper, three-dimensional, unsteady, detached eddy simulation (DES) of a submerged hydraulic jump with an inlet Froude number of 8.2 is performed. The volume of fluid (VOF) method with a high-resolution interface capturing (HRIC) scheme is used for free-surface tracking. The mean velocity and turbulence quantities including the Reynolds stresses are compared with available experimental data to validate the results. The three-dimensional nature of the flow in the developing and developed zone of the submerged hydraulic jump is evaluated by examining the coherent structures using the λ2 criteria. Additionally, proper orthogonal decomposition (POD) analysis reveals the dominance of smaller structures in the developed region of the submerged hydraulic jump. The presence of these smaller scales is directly responsible for the energy dissipation characteristic of the submerged hydraulic jump.

Full frame distilled prediction

Teacher imitation

Not 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.
