Geometrical Model Installation and Deformation Effects in the European Project EUROLIFT II

Kurzfassung

In the EU project EUROLIFT I it has become clear that for a three-dimensional high-lift configuration flow separations at maximum lift may be influenced by the presence of specific geometric effects. To clearly distinguish between these geometric effects an in-depth CFD study has been carried out in the EUROLIFT II project that focuses separately on the spurious influence of model deformation, presence of wind tunnel walls, presence of the model mounting (peniche), and effects of pressure tube bundles on high lift performance. The paper presents the main findings in this CFD study.
