It is found that the abovementioned 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.The work was supported by the Ministry of Science and Higher Education of the Russian Federation, project no. 075-15-2019-1890. Quenching of detonation in channels with barriers was studied with support from the Russian Foundation for Basic Research, project no. 18-01-00883. The work was carried out using the equipment of the shared research facilities of HPC computing resources at Moscow State University.
