The paper presents the results of a numerical study of the interaction of a formed cellular detonation wave propagating in a stoichiometric hydrogen-air mixture at rest in a plane channel, with multiple obstacles (barriers) located on the inner surface of the channel. The influence of geometrical parameters of a domain with obstacles on detonation propagation has been investigated. It has been found that the location of obstacles in the deepening of the channel wall leads to a decrease in their destructive effect on the wave. The possibility of extinguishing detonation by a layer of air located along the channel well, limited by single barriers, has been studied. It has been established that filling the domain with barriers with air or argon enhances their destructive effect on the wave, thereby contributing to suppression of detonation combustion. Keywords:: Plane channel, detonation, multiple obstacles, air layer, failure of detonation. DOI: 10.61011/TPL.2023.09.56717.19657
