Abstract
To simulate the fluid-structure interaction (FSI) of a clamped panel at high speed the DLR flow solver TAU code is coupled with the commercial structure mechanic solver ANSYS. The investigated case is a thin steel panel mounted flush with the wall of a Mach 2 wind tunnel. The panel is excited by a separated shock-boundary layer interaction in turbulent flow. The simulations are based on experimental test carried out in the RC-19 facility at the Air Force Research Laboratory (AFRL) in Dayton/Ohio. Thermal expansion of the structure caused by aerothermal heating leads to buckling of the panel and a change of the pressure in the closed cavity on the back of the panel. In addition to the effects of thermal heating and cavity pressure change the study investigates the influence of structural damping and of the simulated physical time-step size
