Abstract
Within the scope of this paper the behavior of unsteady flow due to oscillating flaps on the airfoil NLR 7301 and the AFMP wing is analysed. For the two-dimensional model, the two flow solvers of DLR (TAU) and ONERA (elsA) are applied. Therefore, a comparison not only with experimental data but also among both CFD-results is carried out. Although it exists a good agreement for this two-dimensional experiment and the numerical solutions, differences in the turbulence models of the codes are exhibited. The three-dimensional delta wing is calculated using TAU. Surprisingly, the experimental data is only partly reproduceable with the CFD code. Despite the existing discrepancies, the nature of unsteady flow due to an oscillating flap can be found in the experiment as well as in the numerical results.
