[1] Levin V. A., Manuylovich I. S., Markov V. V. Formation of 3d detonation in supersonic flows by solid walls of special shape // 30th International Symposium on Shock Waves 1. — Springer International Publishing AG Gewerbestrasse 11, 6330 Cham, Switzerland, 2017. — P. 441–446. This paper presents the results of research on the fundamental problems of detonation associated with new ways of initiation without volume energy supply, in which the decisive role is played by the interaction of gas mixtures with solid boundaries of the flow, the effects of cumulation, and the formation of complex shock wave structures. Besides, this study was carried out to analyze the possible use of solutions of two-dimensional (2D) nonstationary flows of combustible mixture to evaluate the stationary supersonic flows in three-dimensional (3D) channels of variable cross section. In this regard, the results of numerical simulation of detonation in flat chambers with movable walls and detonation in 3D channels of variable cross-sectional size, as well as in 3D helical channels, blown by supersonic flows of combustible mixture, are presented. The study is carried out in a framework of one-step combustion kinetics by numerical method based on the S.K. Godunov scheme [1]. https://link.springer.com/chapter/10.1007/978-3-319-46213-4_75.
