The paper presents the results of a study of the combustion of a propane-air mixture in a cylindrical channel. The relevance of the study is related to the need to study the processes of flame propagation in gas mixtures in closed volumes. The problem is solved numerically for a two-dimensional axisymmetric formulation. The solution method is based on the Van Leer method for calculating mass, momentum, and energy fluxes on the faces of computational cells. The formation of a tulip-shaped flame is shown. It is shown that the results of the numerical study correspond to the experimental data - the formation of a tulip-shaped flame is possible for mixtures with a composition close to stoichiometric. The stages of flame formation correspond to the descriptions from the literature: a flame expanding towards the side wall, an axially elongated flame, a skirted flame, a tulip-shaped flame.
