内容記述 | Involving complicated physical and chemical processes, spark ignition is considered one of the most difficult and complex problems, and it has not yet been explained sufficiently. Minimum Ignition Energy (MIE) is an important parameter to judge the ignition ability of an ignition system. In the present study, the spark ignition characteristics of methane-air mixture were investigated by numerical analysis using detailed chemical kinetics which consists of 53 species and 325 elementary reactions. Two different analytical models with and without electrode were applied to research the effect of electrode temperature and energy channel length on flame propagation and relationship between MIE and equivalence ratio. The electrode temperature is set at 300 K, 1000 K and 2000 K for analytical model with electrode, and the energy channel length is set at 1 mm, 2 mm and 3 mm for analytical model without electrode. The obtained computational results showed good agreement with experimental results. We elucidated that with the increase in the temperature of electrodes, the minima of the curve indicating the relationship between MIE and equivalence ratio move toward to leaner side, that leaner mixture is more sensitive to the heat loss to the cold surrounding gas, and that the heat loss to the electrode is an unignorable factor for the initial formation of flame kernel. | |||||
