title = "Modeling of Hypersonic Flow Over a Cylinder in a Reflected Shock Tunnel Facility",
abstract = "The Direct Simulation Monte Carlo (DSMC) method is utilized to numerically simulate test conditions in the Sandia Hypersonic Shock Tunnel (HST) facility. The setup consists of a hypersonic flow over a cylinder with the freestream at flow speeds of 4-5 km/s in a state of thermal non-equilibrium. We present comparisons of temperatures derived from spectrographic measurements of Nitric Oxide (NO) emission in the ultraviolet (UV) region with predictions from the DSMC solver. Furthermore, we present differences between spectrally banded imaging measurements taken during experiments in the infrared (IR) and UV regions with those obtained from numerical simulations.",
