Many researches devoted to deflagration appearance in hydrogen-air mixes and transition it to detonation. Preference of hydrogen as a fuel is detonation fuel cycle which is more energetic preferable in comparing with ordinary fuel cycle. In connection with this preference problem of hydrogen detonation engine constructing is extreme actual. Essential part of investigations in this field is developing and improving of mathematical methods for numerical simulation of deflagration initiation and transition it to stable detonation. In real physical experiments this deflagration initiation in flows appears via sudden hot spot appearance or near an obstacle on boarding surface. In this paper numerically investigated flows of reactive gas mixes in channels with obstacles with purpose to define regims of deflagration initiation.

有障碍区域氢气-空气混合气流中爆燃出现的计算

许多研究致力于氢气-空气混合物中爆燃的出现并将其转变为爆炸。优选氢作为燃料的是爆震燃料循环，与普通燃料循环相比能量更高。与这种优先选择相关的氢爆震发动机构造问题是极其实际的。该领域研究的重要部分是开发和改进爆燃起爆数值模拟及其过渡到稳定爆轰的数学方法。在真实的物理实验中，流动中的爆燃引发是通过突然出现热点或靠近登机表面的障碍物而出现的。本文对有障碍物的通道中反应气体混合物的流动进行了数值研究，旨在定义爆燃引发的范围。
