Experimental Investigation of Wetted Zone Due an Impinging Circular Water Jet on a Moving Surface
Bibliographic record
Abstract
Cooling liquid jet impingement has many industrial applications such as metal manufacturing where the shape and the size of wetting area around impingement point is important in heat transfer analysis. A series of experiments on a moving surface with an impinging industrial-scale circular water jet is conducted to explore experimentally the wetting region and the hydraulic jump as the front of wetted zone. The effects of surface motion on the wetting zone and the formation and location of hydraulic jump upstream the impingement point is examined by changing systematically the surface velocity and the jet flow rates. The surface motion impacted the radial evolution of wetted zone in all direction and decreased the radius of non-circular hydraulic jump. However, higher jet flow rate suppressed its effect. Both surface velocity and jet velocity or their velocity ratio has to be considered in adjusting jet space along a jet-line in industrial cooling application.

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.
