Abstract
This paper prresents an overview of numerical simulations on unsteady wing nacelle interference for the generic WIONA configuration. The geometry of the model exhibits typical aeordynamic interference effects, including the appearence of a shock in the channel between nacelle, pylon and wing. CFD simulations for the model undergoing forced pitching oscillations show a strong influence of the shocks on unsteady pressure distributions. Three numerical models with varying complexity have been applied, namely unsteady RANS and Euler, both with DLR's TAU code and the unsteady time linearized TDLM code. The fast TDLM code may be applied for attached flow, and results are validated with corresponding ones from Euler solver. If flow separation occurs, the current RANS simulations seem to be necessary.
