Abstract

The modeling of unsteady side loads induced by the interaction of flow separation inside nozzles and launcher wake will play an important role for the design of future propulsion systems. The simulation of this phenomenon, called buffeting coupling, is one of the main challenges during ascent. To investigate the whole nozzle flow field, basic studies of generic configurations by advanced turbulence models are necessary. For this reason the validation of the Detached Eddy Simulation implemented in the τ-code for an axisymmetric supersonic cyl-inder configuration are carried out. Fur-thermore unsteady simulations of the Ari-ane-5 nozzle section are investigated and validated by wind tunnel data.
