Abstract

The Direct Simulation Monte Carlo (DSMC) method is utilized to model unsteady onedimensional (1D) shocks propagating down a shock tube. The computational domain is set up to replicate conditions observed for Shot 26 which is a part of Test Series 66 conducted at the NASA Ames Electric Arc Shock Tube (EAST) facility. DSMC solutions for the 1D shock are used as input for NEQAIR to compute the Nitric Oxide (NO) infrared (IR) and ultraviolet (UV) spectral bands in the shock layer and post-shock relaxation regions. The novelty of this work lies in comparisons of the simulated spectra with experimental measurements made at EAST which provides valuable insight into the performance of the thermochemistry models used in our DSMC solver as well as important thermochemical processes in this flow regime.
