Abstract
This study presents a comprehensive 3D Eulerian-Lagrangian analysis of droplet behavior in an electrostatic rotary bell sprayer operating under pulsed electric fields.The simulations are performed using OpenFOAM, incorporating a Large Eddy Simulation (LES) turbulence model to capture the complex, high-Reynolds-number airflow typical of industrial spray system, along with spray dynamics, electric field modeling, and droplet tracking.The results highlight how pulsed voltage parameters influence droplet dispersion patterns, transfer efficiency and coating uniformity.These findings offer new insights for optimizing electrostatic spray technologies and demonstrate the potential of pulsating electric fields to improve energy efficiency and coating performance in automotive and other industrial applications.

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 it
