A numerical study focuses on the interaction between shock waves and shear layers on the flow physics of an opposing jet by solving RANS. The results successfully replicate two distinct interaction modes, namely LPM and SPM. In addition, it’s find that DMD can enables the identification of the unstable modal structures and relevant temporal frequencies in analyzing the unsteady oscillatory in LPM
