title = "Modeling of Nitric Oxide Vibrational Level Populations Using an Overlay Approach for Emission and Absorption Spectra",
abstract = "Modeling of Nitric Oxide (NO) vibrational level populations is being performed for a flow over a cylinder case with a free stream Mach number of 7.2. The flow field results for the base flow are calculated using the Direct Simulation Monte Carlo (DSMC) method. A collisional-radiative(CR) model has been constructed to compute estimates of the vibrational level populations of NO. The overlay approach is used to couple the CR model with the base flow field by in corporating the CR model into a mass transport (MTR) equation solver. The overlay approach predicts distributions of NO vibrational level populations which differ significantly from those obtained using the Quasi-Steady State (QSS) approximation or the Boltzmann distribution defined at thermal equilibrium conditions.",
