General equations: transport equations for the gas
From what it has been indicated above it appears why interaction between flow and radiation fields occurs: the emission and absorption of radiation can produce neutralization or ionization, or, in any case, a variation of the population in the various levels of energy, and thus contribute to the transport of mass momentum and energy of each species of particles. On the other hand, as a consequence of the flow, changes of pressure, density and temperature of each species, and therefore changes of physical quantities on which the radiation field depends, occur.
