Abstract:

The effect of discharge pulse interval and number on the discharge and ignition characteristics of nanosecond pulse surface dielectric barrier discharge （nSDBD） in NH3/air mixture was studied. The experiment is conducted in a constant volume combustion chamber. Discharge characteristic tests show that nSDBD can generate multiple independently distributed discharge filaments， expanding the range of plasma. When using 30 pulse numbers with a pulse interval of 50 μs， at least 12 discharge filaments are excited， with filament lengths exceeding 14 mm. The ignition characteristic test shows that nSDBD has achieved spatial multi-point ignition. When the pulse interval is 50 μs， 180 discharge pulses generate 6 initial flame kernels surrounding the top electrode. In the NH3/air mixture， there is a phenomenon of initial flame kernels dissipating， resulting in a discrepancy between the number of initial flame kernels and the number of stable combustion flame kernels. As the pulse interval or pulse number increases， the area of the initial flame kernels increases， and the number of stable flame kernels gradually increases from 1 to 6. This effectively shortens the ignition delay of NH3/air mixture， with a reduction of up to 30 ms， approximately 55%. The adjustment of pulse interval and pulse number can effectively control the combustion phase of NH3/air mixture.
