Abstract

Computational fluid dynamics has been used to simulate many high enthalpy flows, however there remain a number of challenges to simulation methods. The simulation of high-enthalpy transitional or turbulent flows is largely beyond our capabilities, as is the simulation of flows with large separation regions. The widely-used thermo-chemical models are still not adequately validated, and recent comparisons with experiments indicate that there may be important errors in the present modeling of the energy transport process. To gain confidence in numerical simulations of high enthalpy flows, new experiments are needed. These experiments must be designed to be sensitive to specific elements of simulation methods and thermo-chemical models.
