Abstract
The present study examines the nature of separation shocks in over-expanded axisymmetric nozzles at a defined pressure ratio under steady viscous flow conditions. Furthermore unsteady computations on hybrid meshes are carried out for simulations of a realistic nozzle configuration. Data of existing experiments in the FFA HYP500 wind tunnel are used in both cases to underline the achieved numerical results. The unsteady simulations show that the viscous shock system in the nozzle can be treated as a damped oscillator.
