Abstract : During atmospheric reentry phase of a spacecraft, its body surface is the seat of complex physico-chemical phenomena. We focus in this thesis on the case where the wall of the flying object has several components ablating differentially. In particular, one of those components undergoes a phase change giving the rise to the introduction of a liquid phase. We have three phases in the domain: solid, liquid and gas phases.The work done in this thesis corresponds to the development of 2D numerical methods which can modelize the different interfaces. The main issue of this thesis is to propose methods and algorithms for coupling the two-phase flow, multi-material heat problems and phase changes (melting and sublimation).
