Prediction Capabilities of Maximum Lift Effects for Realistic High-Lift-Commercial Aircraft-Configurations within the European Project EUROLIFT II

Kurzfassung

Within the framework of the European project EUROLIFT II extensive numerical computations have been conducted aiming to assess the capabilities of CFD to predict the dependence of the high-lift performance on the Reynolds number and to further improve the understanding of the high-lift associated vortex phenomena, especially the nacelle strake mechanism. Within this paper the focus is put on continuative analysis of the results based on the computations performed by DLR using the TAU code. The paper will outline the validation activities, based on LSWT and ETW wind tunnel measurements, forming the base for the assessment of the prediction capabilities conform to the objectives. Additional results will be presented addressing the influence of the computational grid on the predicted high-lift performance.
