Simulation of Ablating Hypersonic Vehicles with Finite-Rate Surface Chemistry

Abstract: For the purpose of predicting the environment encountered by hypersonic, ablating vehicles employing non-charring thermal protection systems, the coupling of a Navier-Stokes solver to both a material response code and finite-rate surface chemistry code is described. The Navier-Stokes solver used in this study is LeMANS, a three-dimensional computational fluid dynamics code used to simulate hypersonic flow fields including gasphase nonequilibrium thermochemistry. The material response solver used in this study … Show more

“…So, sublimation seems to produce a volume ablation whereas oxidation produces clean surfaces. These observations agrees well with the choice made on some ablation models where oxidation is treated as a surface-based degradation whereas sublimation is a volume-based one [42][43][44].…”

“…CFD/ablation coupling has been explored in a number of efforts in the past with varying degrees of coupling. [12][13][14][15] For this work, we have developed the ability to generate aeroheating data using a hypersonic computational fluid dynamics (CFD) code. The CFD code is run at iso-thermal cold wall conditions and the corresponding heating information (typically a heat transfer coefficient, recovery enthalpy and pressure) is mapped from the CFD solution to a non-matching surface grid of the ablation sample.…”
