Аннотация:https://doi.org/10.1134/S1063785020020248WOS:000529352500024, Scopus eid=2-s2.0-850839823232018 JCR Impact Factor (WOS): 0.773 (Q4),https://www.scimagojr.com/journalsearch.php?q=12311&tip=sid&clean=0H=32, (2019) Q2, SJR=0.446, Cites per Doc: 1.009 (20200907)The effect of preliminary preparation of a stoichiometric hydrogen–air mixture (decomposition of a part of molecular hydrogen and molecular oxygen into atomic gases) on the characteristics of a propagating detonation wave is numerically studied using a detailed kinetic mechanism of chemical interaction. It is revealed that this preliminary dissociation leads to a significant reduction in the transverse size of the detonation cell with a slight increase in the propagation velocity of the self-sustained wave, which allows using this preparation to prevent detonation damping in channels with both a single obstacle and multiple barriers.This work was supported by the Ministry of Education and Science of the Russian Federation, contract 14.G39.31.0001 of February 13, 2017). The study of damping of detonation in channels with barriers was carried out with the support of the Russian Foundation for Basic Research, projects nos. 16-29-01092 and 18-01-00883.
