Abstract

The modelling of unsteady side loads induced by the interaction of flow separation inside the nozzle and in the wake of launchers play an important role for the design of main stage propulsion systems. That so called buffeting coupling is one of the main challenges during ascent. Within the last decade various experimental and numerical studies of the problem have been carried out concerning the ascent of the Ariane-5 launcher. Nevertheless the proper simulation of the whole unsteady turbulent flow field of the launcher configuration is still not feasible. To simulate the whole nozzle flow field basic studies of the unsteady flow and the applicability of advanced turbulence modelling is necessary. For the reason isolated nozzle configurations as well as validations of Detached Eddy Simulation for an axisymmetric supersonic cylinder configuration are carried out to earn experience for unsteady simulations of the whole Ariane-5 configuration.
