Numerical Models of Electron Kinetics in the Problem of Transverse Flow around a Cylindrical Model by a Supersonic Gas Flow

The results of a systematic numerical study of nonequilibrium physical and chemical processes in a compressed layer near a cylinder in a transversely streamlined cylinder by a supersonic flow of molecular nitrogen at a speed of similar to 10 km/s are presented. The problem was solved using the author's computer code for integrating the system of complete two-dimensional Navier-Stokes equations, the equation of continuity and conservation of the energy of the translational motion of particles in the form of the Fourier-Kirchhoff equation, the system of equations of physical and chemical kinetics, taking into account dissociation and ionization. A two-level ionization model based on classical ideas about the collision mechanism of ionization is proposed and investigated. Several models of physicochemical kinetics have been studied. A comparison with experimental data is made.
