Abstract

fetched live from OpenAlex

Applying a high-speed gas flow is an effective method to exclude residual plasma and expedite the insulation recovery of high-power spark gaps and can extend their applications to higher-repetition fields. In this paper, the subject of interest is a spark gap repetitively working in a low-damping oscillatory regime of discharge. The influence of gas flow for performance regulation on spark resistance was investigated based on both electrical and optical diagnoses. A high-speed air flow ranging from 0 to 100 m/s was applied by a Laval nozzle, and a significant increase in the damping ratio of the discharge current, implying an increase in spark resistance, was observed with increasing speed of gas flow. According to the optical diagnosis results, the influence of gas flow on the spark channel had two main aspects: configuration and temperature. Although the electron temperature under gas flow showed a trend of slight increase, indicating an increase in the conductivity of the spark channel, the high-speed gas flow could greatly stretch and thin the discharge channel, which was the dominant factor and resulted in an increase in spark resistance.

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.
