プラズマ着火促進のための予混合気中でのナノ秒パルス放電に関する数値シミュレーション

The compression ignition mechanism of PRF90/air mixture assisted by a non-equilibrium plasma has been clarified by 0-dimensional computational simulation. In a compression ignition process of fuel-air mixture, the heat release rate shows three peaks. The primary peak is caused by O radical generation from a thermal dissociation reaction of O₃. With increase of input energy density, gas temperature linearly elevates. While mole fraction of NO_x exponentially rises, O₃ shows maximum value at 4.0 mJ/cm³ and then gradually decreases due to thermal dissociation.
