Premixed flame ignition by transient plasma discharges
Flame ignition by short-duration (≈ 50 ns) transient plasma, or corona, discharges was investigated for methane-air, propane-air and butane-air mixtures at atmospheric and elevated pressures. Such discharges produce a larger fraction of high-energy electrons, yield more spatially distributed energy and deposit energy in the gas more efficiently than conventional arc discharges do. We show that ...

متن کاملAn Experimental Study of Coal Dust Ignition in Wedge Shaped Hot Plate Configurations
Ignition behavior of bituminous coal dust deposited between two hot surfaces forming wedges of 60º, and 90º is experimentally studied. Three thermocouples placed along the symmetry plane of the wedge cross-section at various heights from the apex (lowermost, middle and top) are used to record the transient temperature data. Results show that the ignition always occurs around the region surround...
متن کاملEffect of Fuel Type on Flame Ignition by Transient Plasma Discharges
Rise and delay times of mixtures of methane, propane, n-butane, iso-butane and isooctane mixed with air ignited by transient plasma discharge were investigated and compared with spark discharge ignition. Multi-ignition site effect and high electron energy are suggested to contribute to shortening of rise and delay times.
متن کاملPlasma assisted flame ignition of supersonic flows over a flat wall
A nanosecond pulsed plasma discharge located between two fuel jets is used to ignite and hold jet flames in supersonic crossflows, without the use of additional devices (e.g., cavities or backsteps) for flame holding. The fuel injection nozzles and discharge electrodes are mounted flush with the surface of the flat wall adjacent to the freestream flow. The nonequilibrium plasma is produced by r...
