TABLE 1 CANDIDATES OF LASERS FOR SPACE PROPULSION EXPERIMENTS Fig. 1. Experimental apparatus of supersonic CO2 mixing EDL. supersonic N2 nozzle, instantaneous mixing position at nozzle exit (or mixing section of a finite length from exit), and the mixed flow section in cavity. According to the assumptions of steady, quasi-one-dimensional inviscid flow and of three-mode model of vibrational relaxations in CO2-N2 system, we obtain the equations of the state, mass, momentum and energy conservation as well as three vibrational relaxation equations (5). These ordinary differential equations are numerically integrated from the throat conditions of vibrational equilibrium. With regard to the glow discharge section, discharged energy term is added to the energy conservation equation, and the vibrational relaxation equation of N2 has the additional discharge term per unit N2 mass flux.
