Abstract: Abstract A scramjet is an air breathing jet engine for hypersonic flight, in which combustion takes place at supersonic flow velocity. Fast mixing of fuel and the compressed air flow is thus essential for the efficient operation. Because the penetration depth of fuel injection perpendicular to the main flow direction is very small, strut injectors that are positioned directly within the supersonic core flow are usually used in large chambers. We performed large-eddy simulations for a generic strut-injector geometry. The main objective of this paper is the analysis of the pilot injection for flame stabilisation.
