Collisional Radiative Modelling

The conditions of thermal, chemical and radiative non-equilibrium attained in a pure N2 gas subjected to a strong shock wave were quantified using vibronic-specific state-to-state models.

The Forced-Harmonic-Oscillator model was employed in the computation of rate coefficients for vibrational transition and dissociation of N$_2$ and N$_2^+$ by heavy particle impact. Thermal dissociation...

85. NEW FEATURES OF THE NEQAIR RADIATION CODE

Brett Cruden (AMA Inc/NASA Ames)

The longest-lived code for predicting shock layer radiation, NEQAIR, is now in its 5th decade of service. Substantial changes to the code have been made over the previous decade, the most recent report of which was at the 5th Workshop on Radiation in High Temperature Gases in 2014, for the version referred to as NEQAIR14. This paper will review some of the improvements made to the NEQAIR code...

103. PHOTON MONTE CARLO TRANSPORT COMPUTATION FOR ATHMOSPHERIC (RE-)ENTRY

Reentry into Earth’s atmosphere and entry into the Martian atmosphere can yield to significant radiative heat loads experienced by the flight configurations. For an Earth-atmosphere, the gas is normally considered optically transparent, but very high temperatures behind the shock will radiate, especially in thermodynamic non-equilibrium conditions. CO2 is the main constituent of the Mars...

89. Extension of PARADE with MgO molecule (B-X and B-A systems)

Ms Sara Delahaie (High Enthalpy Flow Diagnostics Group, Institute of Space Systems IRS, University of Stuttgart, Germany and CentraleSupélec, Université Paris-Saclay, France)

The recording of meteor spectra allows a better understanding of meteoric composition and in doing so, also the composition of the parent body [1-2]. The composition of a meteoroid is measured by analyzing the measured radiating species with a simulation software for emission spectra. One software is PARADE (Plasma Radiation Database), a line-by-line emission calculation tool [3]. This...
