When studying the problem of atmospheric reentry we need to model three different physical phenomenons. First, the flow around the atmospheric reentry vehicle is hypersonic, it is characterized by the presence of a strong shock which leads to a rapid heating of the vehicle. We model the flow using the compressible Navier-Stokes equations and the heating of the vehicle is modeled with the anisotropic heat transfer equation. Furthermore the vehicle is protected by an heat shield, where thermochemical reactions, commonly named ablation, occurs. In the first chapter of this thesis we introduce the numerical diffusion scheme CCLAD (Cell-Centered LAgrangian Diffusion) that we use to solve the anisotropic heat diffusion. We develop its non trivial...
