LES of a Transverse Jet into a Supersonic Crossflow

Numerical investigation of a transverse sonic jet injected into a supersonic crossflow was carried out using large‐eddy simulation. Results have been validated carefully against experimental data. Turbulent behaviors relevant to the interaction of the jet and the supersonic crossflow are discussed. The complex flow structures and the relevant flow features are analyzed to exhibit the evolution of shock structures, vortical structures and jet shear layer.
