摘要：A computational analysis of mixing of hydrogen and air has been performed considering scramjet (supersonic combustion ramjet) combustor.Hydrogen is injected at M=1 through the rear of a simple strut located at a distance of 37.54 mm from inlet of combustor.The shape of the strut is chosen in a way to produce strong streamwise vorticity and thus to enhance the hydrogen/air mixing.Strength and size of the vortices are defined by the strut geometry and may be modified.The induced vortices cause an increase in entropy and larger losses in total pressure.
