Abstract: Results of a comprehensive numerical and experimental study of the dynamics of the flow of equilibrium combustion products of stoichiometric acetylene-air mixtures in the exhaust system of a jet engine with an annular nozzle are presented. Results of the numerical solution of unsteady Navier–Stokes equations for a chemically nonequilibrium model of a multispecies gas medium are reported. Experiments are performed in a hotshot aerodynamic setup. Thrust characteristics of the exhaust system of the jet engine are determined, and specific features of the structure of a steady flow formed there are found.
