Effects of EHD and external air flows on electric corona discharge in pin-plate configuration
Bibliographic record
Abstract
The effect of airflow, including the electrohydrodynamic (EHD) flow produced by the electric corona discharge, and the flow generated externally on the corona discharge has been investigated numerically in this paper. Contrary to the common assumption that the corona discharge and the EHD flow can be decoupled by neglecting the convection term in the current density equation, the equations for the electric field, charge transport and fluid flow have been solved simultaneously. The numerical algorithm is based on the boundary and finite element methods (BEM and FEM), the method of characteristics (MOC) and the finite volume method (FVM). The simulation results confirm that the EHD flow has a very small effect on the corona discharge. However, in some configurations the external airflow may have considerable effect on the V-I characteristics of the system and the current density distribution on the ground electrode.

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.
