Overview

This analysis reveals the flow field characteristics and discharge behavior in a three-phase exciter, suggesting improvements in combustion efficiency.

Key Points

  • The three-phase rotary arc exciter enhances combustion by generating reactive particles, aiding chemical reactions.
  • Active particle analysis revealed the presence of excited-state nitrogen and oxygen molecules, beneficial for combustion.
  • The dual-stage swirler design integrates with three needle electrodes to optimize arc discharge performance.
  • Findings show that variations in air flow rates lead to different discharge modes, impacting turbulent intensity.
