Problems and perspectives of state-to-state kinetics for high enthalpy plasma flows (Invited)

Abstract

State-to-state kinetic description of non-equilibrium radiative gas flow AIP Conf.Abstract. The paper will present a brief overview of the applications of state-to-state kinetics in modeling fluid dynamics. The research activities ranges from hypersonic entry (boundary layer, shock wave) to ground test facilities, from MHD interaction to DBD flow control. The state-to-state model in fluid dynamics in the last years is rapidly diffusing, promising new interesting developments in the next future.

State-Specific Study of Air in the Expansion Tunnel Nozzle and Test Section

“…However, accurately characterizing the degree of thermochemical excitation in the experimental freestream is critical for the correct interpretation of experimental data for blunt and slender body studies as well as scramjet studies, and this concept is well documented in literature [4,[14][15][16][17][18][19]. High fidelity state-to-state (StS) thermochemical nonequilibrium models do exist, though their applications have mainly focused on shock waves and converging-diverging nozzle flows where excellent work has been done [20][21][22][23][24][25][26]. Though, as mentioned earlier, converging-diverging nozzle flows are not relevant to the expansion tunnel.…”
