Cfd Implementation Of A Novel Carbon-Phenolic-In-Air Chemistry Model For Atmospheric Re-Entry, Alexandre Martin, Iain D. Boyd

Alexandre Martin

Recent and future re-entry vehicle designs use ablative material as the main component of the heat shield of their thermal protection systems. In order to properly predict the behavior of the vehicle, it is imperative to take into account the gases produced by the ablation process when modeling the reacting flow environment. In the case of charring ablators, where an inner resin is pyrolyzed at a relatively low temperature, the composition of the gas expelled in the boundary layer is complex and might lead to thermal chemical reactions that cannot be captured with simple flow chemistry models. In order to …
