摘要: The present work focuses on the numerical simulation of propagation a premixed flame in one-dimensional confined domain and its interaction with water mist. Main effects are drag, break-up, heating vaporisation droplets. chemical structure is analysed as well gas behaviour. main goal to determine efficiency different barriers mitigate under regimes: deflagration or detonation. Therefore, extinction criterions used. Also, relative importance oxygen dilution quenching established.
