CONCLUSIONS<br />
• 1D Fluid dynamic codes coupled with a self-consistent kinetics<br />
of hdrogen plasma<br />
• Inclusion of atomic Collisional-Radiative model<br />
• Coupling with radiation transport calculation<br />
• Extension to nozzle expansion<br />
• A powerful tool for non-equilibrium radiation modeling<br />
• Extension to other mixtures<br />
