Overview

Randomized trial evaluated gas dynamics in a plasmatorch, indicating electrode shape influences performance.

Key Points

  • To evaluate the influence of two-chamber electrode geometry on gas flow dynamics within a plasmatorch.
  • Used 3D numerical simulation to analyze flow dynamics in a two-chamber plasmatorch.
  • Investigated gas flow velocity, turbulence kinetic energy, and pressure distributions.
  • Conducted experiments comparing cylinder-conical and cylinder-only electrode shapes.
  • Cylinder-conical electrodes showed a 30-35% increase in voltage compared to cylinder-only electrodes.
  • Higher kinetic turbulence energy and wider turbulent zones were observed with the two-chamber design.
  • Shorter initial laminar columns in the electric arc were noted due to the turbulent interval expansion.
