Abstract:

Transient plasma discharges utilizing short 30 to 100 nsec, spatially distributed streamers energized by pulsed power were investigated as a potential new method for flame ignition. Experimental results showed shorter ignition delay and pressure rise time typically by a factor of 3 for methane-air mixtures, as well as higher maximum pressure compared to conventional spark ignition. In all cases significant modification of initial combustion chemistry appeared to be occurring, leading to more effective combustion over a wider range of pressures and fuel composition rates.
