Numerical Modelling of Dielectric Barrier Discharge Plasma Dynamics in Pure and Multi-Species Fluids
Bibliographic record
Abstract
Dielectric barrier discharge (DBD) plasma actuators have been shown to influence several features of surrounding flow fields. This work models DBD plasma generation and movement in quiescent fluids. The work is restricted to plasma dynamics and does not consider the impact on the bulk flow field. A model is developed for an asymmetrically oriented DBD at 1200 V, in atmospheric conditions, operating within pure gases of N 2 , H 2 , CO 2 , CO, and H 2 O, along with various mixtures including a simplified post-combustion environment. Charged particle densities are dependent on rates of ionization and recombination, and simulations show ion densities up to 10 21 m -3 . Plasma velocity is dominated by ion mobility, with averages between 3.90 mm s -1 and 11.59 mm s -1 . Plasma in mixtures is found to exhibit certain qualities of each constituent species, but is generally governed by the major components of the mixture.

How this classification was reachedexpand
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.
