title = "Modeling of Unsteady 1D Shocks Using the DSMC Approach to Estimate Emission Spectra",
abstract = "The Direct Simulation Monte Carlo (DSMC) method has been utilized to model unsteady one-dimensional (1D) shocks propagating down a shock tube. A framework is employed which involves averaging DSMC solution data, sampled at multiple time instances, to obtain a statistically converged 1D shock solution. The extent of dissociation of diatomic oxygen and the quantity of nitric oxide (NO) formed in the domain post-shock is observed to depend primarily on the velocity of the flow upstream of the shock. Regions of thermal nonequilibrium in the flow post-shock are identified and numerical spectra are calculated at 4 locations post-shock.",
