Numerical Analysis of Electrical Parameter Effects on a Nanosecond Pulsed Dielectric Barrier Discharge Actuator
Bibliographic record
Abstract
Dielectric barrier discharge (DBD) plasma actuators are active flow control devices that have shown promising capabilities of enhancing aerodynamic performance. To study the underling mechanisms occurring within the plasma produced by a nanosecond pulsed DBD actuator and the effect the input electrical parameters have on plasma generation, a numerical model has been developed. Because this work is focused on the plasma behaviour, the impact on the bulk flow has been neglected. The plasma properties analysed here include the charged particle densities, surface charge along the dielectric, and the ion sheath propagation. As the applied voltage amplitude and pulse duration was increased, a larger plasma region formed due to the electric field expanding further throughout the domain. The results highlight a significant relationship between the residual surface charge on the dielectric and the propagation of the ion sheath.

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.
