摘要：

基于定容燃烧弹探究纳秒脉冲放电在不同脉冲电压、不同脉冲间隔下的放电特性,比较不同放电参数对甲烷/空气混合气点火成功率和着火延迟的影响.研究结果表明,减小脉冲间隔,可以合理利用脉冲之间的耦合作用,提高放电能量利用率;增大脉冲电压、脉冲数量和减小脉冲间隔可以扩大甲烷/空气混合气的着火界限;增大脉冲电压和减小脉冲间隔均可以有效降低着火延迟.

关键词: 纳秒脉冲放电, 脉冲电压, 脉冲间隔, 点火成功率, 着火延迟

Abstract:

The discharge characteristics of nanosecond pulse discharge at different pulse voltages and different pulse intervals are investigated based on constant volume bomb. The effects of different discharge parameters on the flame success rate and ignition delay of methane/air mixture are compared. The results show that the coupling between pulses can be reasonably utilized and the utilization rate of discharge energy can be improved by decreasing the pulse interval.The ignition limit of methane/air mixture can be enlarged by increasing the pulse voltage, the pulse number, and decreasing the pulse interval. The ignition delay can be reduced by increasing the pulse voltage and decreasing the pulse interval.

Key words: nanosecond pulse discharge, pulse voltage, pulse interval, flame success rate, ignition delay
