title = "Laser-induced breakdown ignition of low-pressure hydrogen-air premixtures",
abstract = "Laser-Induced Breakdown (LIB) ignition of premixed at different equivalence ratios and low pressure is simulated using a high-order (in space and time) numerical algorithm. A neutral chemistry mechanism for combustion is combined with a plasma chemistry mechanism to simulate the LIB ignition over a large time and temperature range. chemiluminescence is estimated using a detailed mechanism for the generation of radicals and a simple one-parameter model for the absorption of chemiluminescence radiation. The effects of lumping of ionized species into their neutral counterparts are examined. It is observed that temperature-preserving lumping yields a good approximation of the fully ionized solution. Good agreement of the flame propagation rate is observed once the flame kernel grows above in radius; the rate of flame propagation is overpredicted for smaller radii. It is observed that the flame is not optically thin. Experimental time histories of chemiluminescence are predicted well, with room for improvement in the absorption model.",
