Abstract—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.

Index Terms—shock waves, vorticity, skin friction drag, compressibility.
