NEWTONIAN AND NON-NEWTONIAN SPRAY INTERACTION WITH A HIGH-SPEED MOVING SURFACE
Bibliographic record
Abstract
Motivated by the need to improve spray coating transfer efficiencies, results are presented from an experimental investigation into the interaction between an air-blast spray and a high-speed moving surface. Three model elastic liquids of varying polymer molecular weight and three inelastic liquids of varying shear viscosity were used to isolate the effect of elasticity and shear viscosity, respectively, on spray impaction behavior. In addition, an industrial liquid friction modifier, KELTRACK™, for use in the railroad industry, was included in the spray tests. High-speed photography was used to examine spray impingement. Ligaments, formed as a consequence of a liquid's viscoelasticity, were observed impacting the surface for the higher molecular weight elastic liquids. The effect of increasing elasticity was shown to increase spray coating transfer efficiencies; this is attributed to a larger proportion of the sprayed liquid reaching the target surface as well as an increased splash threshold on impact. Observations and recommendations were stated regarding transfer efficiency improvement considerations.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
