Abstract [en]

The influence of shear-layer jet interaction on the flow structure generation with multiple jets in supersonic crossflow is investigated by Large Eddy Simulations (LES). A duct geometry is investigated,where the supersonic crossflow evolves in a rather sharp transition between the straight convergent and divergent section and therefore shocks establish. The jet origin location in the divergent section of the duct relative to the narrowest cross-section is significant for the shock pattern structure and the interaction point between the established separation bubble and the jets. The interaction of the separation bubble and the jets plays an important role for the flow structure generation by the jets.
