Modeling Sublimation of a Charring Ablator

Modeling Sublimation of a Charring Ablator

The Hertz-Knudsen analysis is shown to accurately predict the sublimation rate from a charring ablator. Porosity is shown to have a significant effect on the surface temperature. The predominant carbon species found in the vapor is C3, which agrees well with the results of previous investigations.
