Shock interactions in inviscid air and $$\hbox {CO}_2$$–$$\hbox {N}_2$$ flows in thermochemical non-equilibrium

Abstract The present study aims at providing insights into shock wave interference patterns in gas flows when a mixture different than air is considered. High-energy non-equilibrium of and $$\hbox {CO}_2$$ CO 2 – {N}_2$$ N over double-wedge geometry are studied numerically. impact freestream temperature on the interaction investigated by simulating two sets conditions. To this purpose, SU2 solver has been extended to account for conservation chemical species as well multiple energies coupled Mutation++ library (Multicomponent Thermodynamic And Transport properties IONized gases C++) that provides all necessary thermochemical species. An analysis presented with respect existing taxonomy interactions. A comparison between calorically perfect ideal simulations confirms effects greatly influence patterns. When relaxation considered, type VI obtained -dominated flow, both temperatures 300 K 1000 K; air, V six-shock obtained, respectively. We conclude increase large pattern whereas flow does not change.
