Kurzfassung
The aeroelastic assessment of hybrid laminar flow control systems for transport aircraft requires well suited computational models to represent the suction system. This paper presents the application of a non-zero wall-normal velocity boundary condition in the DLR TAU-Code to model an active suction system for laminar flow control. First, the computational laminar velocity profile on a flat plate with homogeneous suction is compared to the analytical solution. Second, the suction boundary condition is tested in combination with a correlation-based transition model and compared to experimental data for a NACA airfoil. In addition, a generic test case is used to demonstrate the effect of a suction system on the steady and unsteady aerodynamics of an airfoil in a transonic, high Reynolds number flow.
