Abstract: The present study proposes a simple model for simulating radiation of high-temperature gases, with the intention of predicting radiative transfers in hypersonic flows surrounding a spacecraft when it enters a planetary atmosphere. This paper presents the methodology and the physical models implemented in an aerodynamics code to account for those specific heat transfers in the flow past a blunt body entering a CO2 atmosphere. The line-by-line radiation models include the atomic lines of the atoms C and O, and the molecular systems of the molecule CO, in the [100-7,000 nm] range of the radiation spectrum. The radiation transfers are computed according to a ray-tracing method. Analyses are done to understand the radiative behaviour of the high-temperature gases. The cumulated radiative heat fluxes to the surface of the spacecraft are compared to other computed radiative heat transfer results for verification purpose.
