NEQAIR v15.x, Nonequilibrium Radiative Transport and Spectra Program(ARC-15262-1B)

NEQAIR is NASAs most long standing radiative heating code for flight predictions and simulating experiments. It is a line-by-line radiation code that computes spontaneous emission, absorption and stimulated emission due to transitions between various energy states of chemical species along a line-of-sight through a non-uniform gas mixture. This allows NEQAIR to calculate the radiative heat flux and detailed spectra at a specified location. NEQAIR v15.2.2, which includes v0.3 of the GUI, has focused on improving physics, solution robustness for 3D and coupled calculations, and providing more control for running the code.
