• Ignition of Rapid Compressed CH_4-Air Pre-Mixture by ArF Excimer Laser

抄録

The purpose of this study is to investigate the effect of supplying 0 radicals generated by ArF excimer laser irradiation on the ignition of a CH_4-Air mixture. The laser-induced ignition experiment was performed in CH_4-air mixtures using a Rapid Compression Expansion Machine (RCEM). To study the ignition process, the pressure in the combustion chamber was monitored and OH^* chemiluminescence images were taken using a high-speed camera. The laser-induced ignition was classified 3 patterns ; point ignition, line ignition and ignition near the window. These ignition patterns were decided by the magnitude of the absorption cofficient of oxygen and the ignition types and locations were predictable if the absorption coefficient was known. Then, we evaluated the advantages of applying the laser bulk ignition technique by comparing the pressure profiles with high laser power and with minimum laser ignition power. It was considered that 0 radical generation along the laser beam path caused to reduce the ignition delay and enhance the combustion rate after the ignition.
