Kurzfassung

The paper describes numerical studies by DLR devoted to the computation of the DLR F-11 high lift configuration as part of the 2nd phase of the AIAA High Lift Prediction Workshop. The model geometry is representative for a wide-body commercial aircraft with a classical three element high lift system at the wing leading and trailing edge in a landing setting. Being a follow-up of the NASA Trapezoidal wing of the 1st phase of the workshop, the F-11 wing/body wind tunnel model features only a modest overall complexity increase in the basic set-up. Yet, the most complex geometry representation includes model details, such as slat tracks, flap track fairings, and pressure tube bundles. According to the available experimental evidence, low and high Reynolds numbers have been investigated. In addition to force, moment, and pressure distributions, surface streamlines have been analyzed. The studies have been carried out using the DLR TAU code in conjunction with the Spalart-Allmaras turbulence model in the original formulation. DLR contributed to the grid generation activities by providing a set of hexahedral-based hybrid unstructured grids for all complexity stages and both Reynolds-numbers. For the most simplified configuration, a family of three grids has been generated to study grid resolution aspects. In general, a good agreement to the experimental data is obtained. It turns out that for the present wind tunnel configuration, the inclusion geometry details of the wind tunnel model, such as slat tracks and even pressure tube bundles, is essential for the agreement to the experimental evidence and the prediction of maximum lift.
