Abstract

This paper presents a strategy to investigate the influence of inflow disturbances on the performance of high-lift airfoils in numerical simulations. The method relies on the algebraic delayed detached-eddy simulation (ADDES), which alows a flexible introduction of synthetic turbulence to trigger the scale resolving mode of the turbulence model. First it is shown that the flow separation is sensitive to the position of the synthetic turbulence injection. Then the ability of the method to predict the influence of a generic vortex on a DLR F15 two-element airfoil is demonstrated.
