Abstract

fetched live from OpenAlex

Abstract A numerical algorithm is proposed for simulation of the dielectric barrier discharge plasma actuators including photo-ionization. The computational bottleneck related to a very long computing time has been circumvented by suppressing the discharge pulses and proposing a mean discharge model. It incorporates an artificial damping term into the electron transport equation to suppress the formation of pulses, which significantly accelerates the simulation. Based on the fluid description of three generic species: electrons, positive and negative ions, the model accounts for the drift, diffusion, and reaction terms. The reaction coefficients are extracted from the Boltzmann equation considering the local field approximation. A self-sustained discharge is achieved by including photo-ionization during the positive voltage phase, and the secondary electron emission from the metal surface, during the negative voltage phase. The proposed methodology compromises the computational burdens of the first-principle approaches and inadequacy of the simplistic models in incorporating the problem physics. The accuracy of the proposed methodology has been validated by comparing the computational and experimental data for the electrical and flow characteristics of a laboratory actuator.

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.
