Ultrafast heating and oxygen dissociation in atmospheric pressure air by nanosecond repetitively pulsed discharges

Transient Plasma Impact on Spectra of Flow Disturbances in a Corner Separation Zone at Mach 4.5

“…Thermal dissociation rate constant. a -reaction O2 (thermal) = O + O [k]=m 3 /s [35] ; b -reaction N2*+O2=N2+O+O -quenching rates of N2(C) by O2 [36] .…”

Influence of nanosecond repetitively pulsed discharges on the stability of a swirled propane/air burner representative of an aeronautical combustor

“…Electric pulses of 10 ns in duration are created at the repetitive frequency f 30 = 30 kHz, except for one test where the repetitive frequency is fixed at a value of f 11 = 11 kHz to study the influence of this last parameter. The discharge operates in the nanosecond spark regime, as defined in [17][18][19] with peak currents of the order of 50 A during the 10 ns pulse. For the 30 kHz repetition frequency case, the peak voltage across the load is about 14 kV and the mean power provided by the discharge is about 350 W, to be compared with the flame power P = 53 kW (thus the plasma power is about 0.7% of the power released by the flame).…”

Fast gas heating in N 2 /O 2 mixtures under nanosecond surface dielectric barrier discharge: the effects of gas pressure and composition

“…These conditions are met in high-voltage nanosecond discharges that are being increasingly used for aerodynamic flow control [8,9], plasma-assisted combustion [10][11][12], material processing [13] and for some other applications. That is why much attention has been given to experimental [6,[14][15][16][17][18] and computational [6,7,[19][20][21][22][23] studies of fast gas heating in nanosecond discharges and in their afterglows. Available measurements are usually limited by not-too-high values of E/N.…”
