Effect of the plasma location on the deflagration-to-detonation transition of a hydrogen–air flame enhanced by nanosecond repetitively pulsed discharges

Plasma-assisted combustion of hydrogen swirling flames: Extension of lean blowout limit and NOx emissions

“…Regarding hydrogen, plasma-assisted combustion of pure H 2 has focused mostly on the ignition enhancement [17], in supersonic conditions [18], at low pressure (0.2 bar) [19] and at high pressure (1-12 bar) [20]. A recent study also focused on the deflagration to detonation transition using NRP discharges and showed that the plasma accelerates the hydrogen combustion [21]. Despite these promising effects of NRP discharges on H 2 /air combustion, to the authors' knowledge no studies have focused on the extension of the lean blow-out limit.…”
