Using the detailed kinetic mechanism of chemical interaction, the effect of preliminary preparation of the stoichiometric hydrogen-air mixture (dissociation of a part of molecular hydrogen and oxygen on atomic gases) on the detonation wave characteristics is investigated numerically with the aim to control detonation combustion in plane channels with obstacles. It is found that the above-mentioned partial initial dissociation can be used to prevent quenching of detonation in channels with both a single obstacle and multiple barriers. It is revealed that the mixture, obtained as a result of preparation, differs from the initial hydrogen-air mixture by the qualitatively different type of detonation re-initiation after interaction with obstacles.

使用初步气体混合物制备控制有障碍物通道中的爆震波

利用化学相互作用的详细动力学机制，数值研究了化学计量的氢-空气混合物的初步制备（部分分子氢和氧在原子气体上的解离）对爆轰波特性的影响，以控制爆轰燃烧。在有障碍物的平面通道中。发现上述部分初始解离可用于防止具有单个障碍物和多个障碍物的通道中的爆轰猝灭。结果表明，作为制备结果的混合物与最初的氢气-空气混合物的不同之处在于与障碍物相互作用后爆炸重新引发的性质不同类型。
