The method of numerical integration of the nonstationary two-dimensional equations describing the essentially subsonic motions of a reacting gas is used to investigate the characteristics of the shape and structure of the flame from propagating in a plane closed channel. It is shown that at fairly high Reynolds numbers a two-humped front shape ({open_quotes}tulip{close_quotes}), caused by the development of hydrodynamic flame instability, is formed.
