A numerical study of two-dimensional cellular detonation of a hydrogen-air mixture in channels of various widths was carried out and data were obtained on the process of formation of a cellular structure, on the number, shape, and size of cells depending on the channel width. Based on the results of calculations, a classification of two-dimensional cellular detonation structures was carried out. The study was carried out at the facilities of the JSCC RAS. The flow model of a multicomponent reacting mixture was implemented using a customized opensource solver of the OpenFoam framework based on the Kurganov–Tadmor scheme.
