Advanced Physical Models and Numerical Methods for High Enthalpy and Plasma Flows Applied to Hypersonics
Abstract
This report results from a contract tasking von Karman Institute for Fluid Dynamics on modeling of high enthalpy flows. Collisional-Radiative models for the noble gases have been detailed which included atom and electron-impact processes as well as radiative processes. These models are intended to support plasmadynamic simulations under conditions of high non-equilibrium. The data has been presented in terms of angle-integrated cross sections where we have no assumption of the distribution function has been assumed. This leaves open the possibility to compute the CR rates using an arbitrary distribution function, including a bin approach. While detailed validation has been provided for argon, results for krypton and xenon are still preliminary. Work is currently underway to increase the level of sophistication. These models will be refined and benchmarked against further experimental data, including expansion flows in which radiative processes dominate.
