title = "Collisional Radiative Model to Estimate Nitric Oxide Vibrational Level Populations in High Mach Number Flows",
abstract = "A collisional radiative (CR) model for Nitric Oxide (NO) has been developed to characterize the state-to-state transitions of the vibrational states of NO through collisional and radiative processes. The CR model has been incorporated into a mass transport equation (MassTR) solver to estimate vibrational level populations of NO for a canonical setup of a hypersonic flow over a cylinder. The MassTR solver has been overlayed over flowfield results calculated using the Direct Simulation Monte Carlo (DSMC) method. Furthermore, the DSMC calculation is sampled in the wake regions to obtain estimates of the vibrational states of NO based on the energy distribution in the vibrational modes. Comparisons between these sampled distribution functions and the ones obtained from the MassTR solver help assess the validity of the mass transport approach and the performance of the CR model.",
