Taking into account radiation effects is a crucial part of the design and optimization of applications involving high temperatures. This paper outlines the development of a predictive coupling model for steady state conjugate heat transfer problems including radiative boundary conditions that models radiative exchanges between gray walls in a transparent medium. This canonical model is based on the Godunov-Ryabenkii normal mode analysis theory. The general expression of the amplification factor, the stability bounds and the optimal coefficients are provided. Moreover, a numerical Biot number including radiation effects that controls the stability of the model, is proposed. The destabilizing effect of radiation is highlighted and quantified. A specific test case is then presented to evaluate the consistency of this model. The numerical and physical parameters of this test case were specifically designed to target large fluid-structure interactions (ceramic material, high radiative coefficient). The numerical results fully comply with the theoretical results derived from the predictive model.

“…In the forebody, the radiation is dominated by visible and UV emission of CO, CN and O 2 [2? ]. In the afterbody, the recombination of CO 2 is responsible for a radiative heat flux larger than convective heating [3], but thee are still large uncertainties on the radiative fluxes [4]: on the eve of new Mars missions, a renewed computational [5] and experimental effort was engaged at NASA [4], JAXA [6] and UQ [7] to model nonequilibrium CO 2 radiation.…”

Nonequilibrium infrared emission spectra representative of a Mars atmospheric entry mission are modeled using RADIS, a spectral code for CO and CO 2 based on the HITEMP-2010 and CDSD-4000 databases. The modeled experimental data for the free-flow and the forebody radiation were obtained in the JAXA expansion tube facility. In the expanding flow, good agreement with the experimental data can be obtained using a slightly nonequilibrium distribution and a homogeneous flow. The model suggests that all three CO 2 vibration modes share a * Ph.D student, CentraleSupélec,

The calculation data on convective and radiation heating of the Pathfinder space vehicle (SV) dur ing entry into the Martian atmosphere at an angle of attack are presented. Comparison with the results of cal culations of convective heating of the frontal surface of the Pathfinder SV in the axisymmetric statement is carried out. The data on the radiation heating of the Pathfinder SV entering the Martian atmosphere at an angle of attack have been obtained for the first time. The analysis of the spectral composition of the thermal radiation reaching the surface of the space vehicle is carried out; this makes it possible to mark the change of modes of the radiation heating.
