Abstract

The 3D Parallel-Multiblock URANUS code has been extended by models for radiative exchange between the surface elements and for heat conduction within the TPS (Thermal Protection System). The coupling of the newly developed models with catalytic effects for the real TPS, predicted by a global catalysis model, and with temperature dependent emissivity leads to significant differences in surface temperature distribution. Results for the X-38 re-entry vehicle will be discussed in some detail. Large memory and computational time requirements arise in order to solve the non-equilibrium Navier-Stokes equations on 1.02 million cells coupled with the surface models.
