309 化学動力学を用いた水素自着火反応の計算(OS-1 着火・燃焼解析,噴流解析,研究発表講演)

For finding the optimal design and operating condition in the hydrogen combustion system, it is necessary to consider the spontaneous-ignition characteristics. In this study, detailed chemical kinetics were applied to calculate the ignition processes of the stoichiometric hydrogen mixture, Explosion limits were well predicted under consideration of the adequate heat-loss. Based on the results, the ignition mechanism and the effect of heating rate on the ignition temperature were discussed.
