Intercalibration Results. A Conservation-Law Form of the CMA In-Depth Ablation Model

The Aerotherm CMA code and associated model are the basis for most present in-depth ablation and thermal response analysis methods. In this poster, we re-examine the basic governing equations and recast them in conservation-law form, which is more amenable for use with current computational methods. The basic approximations for the CMA model are retained, and the results are compared to the solution of the CMA form of the equations for the TACOT test problem. The use of a Darcy Law for the pyrolysis gas flow and the assumptions associated with the pyrolysis gas state are also investigated
