Deformation of a Two-Dimensional Trace Pattern of a Detonation Flow with a “Continuous” Change in the Width of a Flat Channel

Abstract

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 and on the number, shape, and size of cells depending on the channel width. Based on the results of calculations, classification of two-dimensional cellular detonation structures was carried out. This study was carried out at the facilities of the Joint Supercomputer Center, Russian Academy of Sciences. 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.
