Due<br>to the change in material properties, the debris thermal behavior will be modified, e.g. the changes in<br>emissivity and conductivity will affect the heat transfer by radiation and conduction, respectively. This<br>work presents numerical tools developed to quantify and evaluate the importance of oxidation on the<br>heat transfer mechanisms of reentering metallic debris. To achieve this, the oxide mass and thickness<br>gains of Invar-36 oxidized in air plasma are numerically simulated in a 1-D finite difference framework.<br>Moreover, a fully coupled mass-heat equation system is implemented allowing investigations of the thermal<br>behavior of reentering oxidizing materials. The analysis is focused both on the surface effects of oxidation<br>(emissivity change, heat of oxidation reactions) and in-depth effects caused by the changes in material<br>properties (thermal diffusivity). CFD simulations are performed to retrieve the Stanton number and<br>obtain explicitly the convective heat flux-wall temperature dependency. The influence of oxidation on<br>the debris temperature is studied with six test cases representing full oxidation modelling, modelling of<br>the emissivity changes, and no oxidation modeling at different flow conditions. Based on this analysis,<br>neglecting oxidation induces an over-prediction of the material ablation and that in-depth modeling is<br>necessary depending on the particular boundary conditions of the problem.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-310.pdf\" data-type=\"link\" data-id=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-310.pdf\">Read the full paper > <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>P.
