Abstract
This document describes the DLR subsonic and separated parts CFD rebuilding and extrapolation activities performed in the frame of the EXOMARS Advanced CD2 phase within work package 1.5.1. Seventeen different flow conditions from the experimental DNW campaign in the HST facility as well as flight conditions have been simulated employing the DLR CFD code TAU in order to determine the aerodynamic coefficients of the vehicles under investigation. Ten initial grids have been generated to properly describe the different geometries and flow conditions. All grids were adapted several times to obtain grid converged results. While the supersonic flow conditions showed a stable behaviour all subsonic cases indicated unsteady flow conditions. Therefore, three of the DNW rebuilding cases have been computed time resolved.
