Assessment of Quarter Cylinder Obstacles Effectiveness on Hydraulic Jump in Rectangular Channels
Bibliographic record
Abstract
In this paper, the effect of quarter cylinder obstacles on hydraulic jump in a rectangular channel has been studied in the laboratory. The quarter-cylindrical obstacles with 2 and 3 cm diameter are considered and the effect of their position and height are studied in the hydraulic jump parameters such as location, energy dissipation and Froude number. The flume used in this research has six meter long, 20 cm wide and 30 cm height. The reason of quarter-cylindrical shape selection for obstacles is reduce the amount of erosion relative to other shapes such as rectangular and trapezoidal obstacles. The obstacles are installed at the end of the channel. Distance between the first obstacle and the beginning of the channel is constant. Totally, 44 tests have been carried out in this research. The results show that increasing distance between the obstacles to a certain amount, increases energy dissipation. But energy dissipation decreases for further distance. Furthermore, optimum s/r increases with increase in the obstacles height.

How this classification was reachedexpand
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.
