Experimental laboratory waves with a plunger-type wavemaker in waves-against-flow conditions
Bibliographic record
Abstract
In this paper, a series of experiments was conducted to further expand the experimental benchmark of tests for plunger-type wavemakers in a laboratory water channel. The tests focus on the generation of waves in waves-against-flow conditions to study the impact of flow relative to the theoretical model given by the Plunger-Type with Flow (PTF) model and the Equal Volume with Flow (EVF) model. Both regular waves and irregular waves were studied for a range of mean flows through the channel and the accuracy of the theoretical wave parameters are quantitatively assessed. For regular waves, it was found that the EVF model is generally more accurate than the PTF model, especially under flow conditions. Additionally, wedges with a larger inner angle are less effective for wave generation, particularly for lower flows. For irregular waves, less errors in significant wave height were observed in the waves-against-flow conditions compared to waves-with-flow conditions, while the dominant wave frequencies were preserved in both conditions. By separating the incident spectra from that of the reflected one, a previously proposed correction for the PTF model was also addressed, validating its experimental applicability across a range of irregular spectra and flow conditions.

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.
