Abstract
The study of water hammer flows has great significance in a wide range of industrial and municipal applications including power plants, petroleum industries, water distribution systems, etc. The understanding of water hammer phenomena is also important in hydraulic conveyance systems such as stormwater and sanitary sewer systems. Although the latter two systems are generally designed based on gravity flow, in practice large variations in the inflow and outflow from these systems may result in the pressurization of the systems that, in turn, may produce water hammer phenomena. For modeling this type of flows, several numerical approaches have been proposed. The efficiency of a model is a critical factor for Real-Time Control (RTC), since several simulations are required within a control loop in order to optimize the control strategy, and small simulation time steps are needed to reproduce the rapidly varying hydraulics RTC is becoming increasingly indispensable for industrial and municipal applications in general. For instance, in the case of water distribution systems, RTC facilitates delivery of safe, clean and high-quality water in the most expedient and economical manner.

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
