WMLES of SBLI with Flexible Panel Motion Predicted A Priori Using an Aeroelastic Solver

An approach to incorporate the motion of a flexible panel under an impinging shockwave/ boundary-layer interaction (SBLI) at Mach 2.5 into a wall-modeled large eddy simulation (WMLES) is developed and implemented. The panel oscillations predicted by an aeroelastic code are used to augment the flow field at the wall with pressure and velocity fluctuations according to the panel’s vibration. The effect on the overall shock structure, separation bubble, wall pressure frequencies, and downstream flow field are compared to an experiment at matching flow conditions. The approach and its effects on the flow field are evaluated with good agreement obtained between the measured and modeled results.
