Kurzfassung
A common research project (CRP) of ONERA and DLR, the CRP LEAFCO (2012-2015), tackles the application of zero-net-mass-flux (ZNMF) actuation on a laminar high-lift airfoil by means of wind tunnel experiments and simulations. Here only numerical results are discussed. The capability of modern numerical methods, unsteady Reynolds-averaged Navier-Stokes (uRANS), to predict the impact of the AFC application on the aerodynamic performance is here used to optimize the unsteady actuation parameters prior the manufacturing and testing of a high-lift airfoil DLR-F15LLE (Laminar Leading Edge). The main objective is to define geometrical parameters of the actuation slit, such as position, direction and width, which are to be considered for the extensive wind tunnel testing with ZNMF-actuators in large test facilities of ONERA and DLR.
