Kurzfassung
Fundamental requirements for future launcher technologies are a cost-efficient access to space as well as the improvement of safety and reliability. In the presented contribution an unsteady turbulent flow simulation of the Ariane-5 launcher during ascent will be carried out by detached eddy simulation (DES). In a first step the nature of separation shocks in turbulent over-expanded axisymmetric nozzles is simulated. Different implementations of detached eddy simulation models are investigated for a compressible wake flow as a validation case. Finally steady and unsteady Ariane-5 simulations are carried out at Mach 0.8 wind tunnel conditions including jet flow and the wake of the boosters.
