摘要

The paper describes numerical investigations within the framework of the 3rd AIAA High Lift Prediction Workshop using the TAU code of DLR (German Aerospace Center) and the SOLAR grid generation package developed by a UK partnership including ARA (Aircraft Research Association Ltd.). Two test cases have been analyzed: the NASA CRM Wing/Body high lift configuration and the JAXA JSM Wing/Body/Nacelle/Pylon configuration. For the JSM, two approaches for the generation of the computational grids have been applied by DLR and ARA, featuring different grid topologies and resolution. The numerical results are based on a widely identical set of solver parameters and analyzed for both approaches in terms of lift and pitching moment coefficients, pressure distributions, surface streamlines and compared to experimental data. Differences between both approaches are discussed. As for many of the workshop results, both sets of numerical results exhibit an overprediction of a separation at the outboard wing aft of a slat track fairing compared to experimental evidence for higher angles of attack. Moreover, differences at the inboard wing trailing edge region are observed. For the CRM configuration, results of DLR are presented using the TAU/SOLAR tool suite. In this context, a global grid refinement study has been carried out. The impact of grid refinement on three grid levels is analyzed by evaluating global coefficients, pressure distributions, as well as velocity profiles on the fixed wing. The comparison of the numerical results is revealing only small differences between the three grid levels under consideration.
