Validation of Models via Comparison with Data for Non-equilibrium Near-Continuum Hypersonic Flows
Abstract
The team has studied the impact of increasing the fidelity of high temperature molecular collision models on key surface, flow, and signature properties for Air Force relevant hypersonic conditions. In this work, we have leveraged the high fidelity real gas effect kinetic models developed over the first two years, and applicable to particle simulations and specifically the direct simulation Monte Carlo (DSMC) method. The models include vibrationally coupled dissociation and recombination, 3D forced harmonic oscillator (FHO) for vibration-translation (V-T) energy transfer, and the near-resonant vibration-vibration (V-V) transitions. Several research directions have been pursued to achieve the goals.
