Abstract

fetched live from OpenAlex

A free surface liquid jet impinging on a moving wall is relevant to many industrial applications including surface coating, cooling and cleaning. Depending on the flow variables, the impingement can be steady (deposition in the form of a thin film or capillary thread) or unsteady (splash or spreading into hydraulic jumps). This study focuses on the steady regime where a Newtonian liquid jet impinges on a moving wall and then spreads into a U-shaped lamella. We particularly focus on the parameter space of jet Reynolds number (Rej) from 50 to 1200 and wall-to-jet velocity ratio (Uw/Vj) from 0.6 to 6. Boundary layer theory is utilized to analyze the spreading characteristics of the lamella. The non-dimensional lamella heel length, Lh/d (d is the jet diameter), and lamella width Lw/d, are solely functions of Rej and Uw/Vj. Our theory predicts that Lh/d and Lw/d scale with Rej 1/3 . With further insight provided by numerical simulations, we found that (Lh/d, Lw/d) roughly scales with (Uw/Vj) 1/2 . These scaling relationships are verified against experiments.

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.
