Popis: | A computational platform was developed to study radiation of high-temperature gases during atmospheric reentries. This platform includes a 2-D axisymmetrical Navier-Stokes solver and a radiative heat transfer solver based on a Monte Carlo method. In this paper, only gas radiation occurring during entries in the Martian atmosphere is considered. Gas radiative properties are obtained using a statistical narrowband model for CO and CO 2 molecules in high-temperature and low-pressure conditions. Computations on a test case related to the Mars sample return orbiter enabled us to set up a calculation methodology that includes a loose coupling of aerothermodynamics and radiative transfer. Monte Carlo band model calculations are validated against line-by-line calculation and a ray-tracing method. Results show that radiative fluxes on the rear part are important in comparison with convective fluxes. They are mostly due to CO 2 infrared radiation. The effects of radiative transfer on the flow structure and temperature fields in both the front shield and the wake regions are discussed. |
