纳秒火花放电是最有前途的燃烧增强等离子体之一。旋转纳秒火花稳定稀薄旋转火焰的直接可视化说明了空气动力学，等离子体和燃烧动力学之间的耦合。虽然人们普遍认为等离子体的热效应和化学效应都可能起作用，但对放电影响火焰的机制尚未有全面的了解。
Nanosecond spark discharges are among the most promising plasmas in view of combustion enhancement. The direct visualization of rotating nanosecond sparks stabilizing a lean swirling flame illustrates the coupling between aerodynamics, plasma, and combustion dynamics. Although it is commonly acknowledged that both thermal and chemical effects of the plasma may play a role, comprehensive understanding of the mechanism by which the discharges affect the flame has not been achieved yet.
