The melting and dripping speed of the copper electrode tip is influenced by arc power, and in some high-power arc cases, heat transfer to the electrode does not reach a stable state before arc extinction, thus the electrode temperature does not always scale with arc power. By analyzing the arc power and arc duration based on the volt-ampere characteristics of the arc and its heat transfer characteristics to the electrodes, it was found that while an increase in initial current and power supply voltage enhances arc power, it also accelerates electrode consumption, thereby shortening the arc duration.

Numerical simulations based on the Reynolds-Averaged Navier-Stokes method have been conducted to investigate the effect of multi-hole film interactions on thermal protection and drag reduction performances under supersonic condition in a supersonic combustor. The results indicate that multi-hole discrete film jets achieve better cooling efficiency and broader cooling coverage under supersonic incoming flow conditions compared with subsonic incoming flow at the same blowing ratio. Under subsonic condition, the small velocity difference between the multi-hole discrete film jets and the main flow exacerbates the penetration of the transverse jet into the main flow, leading to a decrease in cooling efficiency. Smaller lateral hole spacing (<em>P/D</em>) is better for combustion drag reduction and thermal protection performances under supersonic conditions, as it enables neighboring jets to form anti-kidney-type vortex pair structures and creates a cracking heat absorption region. Furthermore, the axial hole spacing (<em>S/D</em>) in aligned multi-hole discrete film jets significantly enhances thermal protection performance by regulating the chemical reaction of hydrocarbon fuel and extending the cracking reaction region. Secondary hydrocarbon-fueled film injection extends the cracking reaction region and delays the onset of the combustion heat release zone, thereby expanding the effective cooling region.
