Abstract

fetched live from OpenAlex

Experimental results for several trashrack models placed in a pressurized rectangular conduit are presented. The tests were performed for both straight and oblique approach flows. Trashrack models of different bar cross-sectional shapes, bar thicknesses, bar depths and bar spacing were studied for a range of velocities. The results indicate that the head loss across the trashrack increases with increasing approach velocity, flow inclination, and blockage ratio. Lower head losses were observed for bars with cross-sectional shape other than rectangular. Results were found to differ only moderately from the previous trashrack energy loss literature based almost entirely on open channel flow experiments. An equation has been developed that well represents the current experimental findings.

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.
