Abstract
The paper discusses CFD solutions on 3 different wing-tip devices (clean tip referred to as Kuechemann-tip, tip-fence and large winglet). Work was performed within the framework of the EU-project M-DAW (Modeling and Design of Advanced Wing tip devices). Solutions on the different tip-devices will be compared with experiments at different Mach- and Reynolds numbers on - a high-speed wing/body configuration (no engines) in the ETW wind tunnel (M=0.85, Remac = 54 millions) and - two different low-speed configurations (cruise and take-off, with engines installed) in the DNW-KKK wind tunnel (M=0.2, Re-mac = 7 to 9 millions). Most solutions appear in fair agreement with the experimental data. However, specific model deformations in ETW have to be accounted for in order to improve the high-speed results. Afterwards the methods/tools used here may be taken as valid for final assessments of brand-new wing-tip device developments within the M-DAW project.
