COLLISIONAL-RADIATIVE MODELING OF QUASI-THERMAL AIR PLASMAS WITH ELECTRONIC TEMPERATURES BETWEEN 2000 AND 13,000 K .2. 2000 K-LESS-THAN-OR-EQUAL-TO-THETA(E)LESS-THAN-OR-EQUAL-TO-4000 K

To extend the validity limits of a collisional-radiative model created to describe a homogeneous and stationary air plasma for electronic temperatures lower than 4000 K, radiative processes, electron-heavy particle and heavy-heavy particle inelastic collisions are taken into consideration in the rate equations of the excited levels. The effects of radiation escape in a monothermal plasma and of radiation escape together with the non equipartition of the kinetic energy in a two-temperature plasma are discussed. One application deals with diagnostic methods using molecular spectroscopy.
