Broadband suppression of aerodynamic pressure on the high-speed bluff body surface with periodic square-cavity acoustic metasurface

In this paper, a Multiphysics coupling simulation model of flow and acoustics is proposed using COMSOL software, and its results are verified by comparing with experimental results of others.Then, the aerodynamic pressure above the bluff body surface at a speed of 350 km/h is simulated.Moreover, a near-zero-impedance acoustic metasurface composed o
