Abstract

Demands concerning geometrical detail arising in the simulation of certain flow phenomena in helicopter interactional aerodynamics can only be dealt with in an unstructured simulation environment. This work deals with the extension of the simulation capabilities at IAG to an unstructured flow solver. The new approach is validated against and compared to the standard structured flow chain in the context of isolated weakly CFD-CSD coupled simulations in wind tunnel conditions corresponding to the low-speed pitch up case of the GOAHEAD experiment. Generally, good agreement between the two respective toolchains is shown. All computations performed herein were conducted using the massively-parallel NEC Nehalem platform at HLRS.
