Interaction between DC discharge plasma and supersonic flow around the leading edge of a flat plate airfoil
Bibliographic record
Abstract
This paper describes the experimental results of the effects of the DC discharge plasma on a supersonic airflow under the condition of applying a magnetic field. The experiments were conducted in an indraft supersonic wind tunnel installed with the Laval nozzle. The DC discharge plasma was generated between a pair of electrodes mounted on the leading edge of a flat plate airfoil surface. Current and voltage measurements indicated that the plasma was generated at low power consumption. From the visualization image of the flow field, the oblique shock wave at the leading edge of the airfoil was observed. Moreover, a slight change in the angle oblique shock wave was seen when the plasma was generated in the magnet field. This tendency shows that a Mach number near the leading edge of the airfoil changed due to the Lorentz force. To clarify the effects of the plasma on the supersonic airflow, total pressure distributions were also measured. We found that the total pressure near the plasma discharge might be higher than without discharge. It was suggested that an enthalpy elevation owing to the discharge led to the increase in the total pressure.

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.
