Combustion of methane injected into an air flow with high subsonic velocities by different methods

Abstract

An important stage of the development of promising engine and propulsion systems is provision of an effective process of hydrocarbon fuel combustion. There are many publications with numerical and experimental data on combustion of various gaseous hydrocarbons under laboratory conditions, but there is a lack of data on effective combustion of hydrocarbons in short combustion chambers with a large number of injectors. Results of systematic experimental studies of natural gas (methane) combustion in a high-velocity subsonic air flow in an air-breathing model combustor with a rectangular cross section are presented in this paper.
