Abstract

The work aims to propose a noise suppression method based on the front-wall resonant cavity to address the issue of cavity noise under supersonic flow conditions, and explore the influence of the three parameters of the front-wall resonant cavity on the cavity noise suppression effect under supersonic flow conditions. A numerical investigation combining Large Eddy Simulation (LES) and Computational Aeroacoustics (CAA) was conducted to study the aerodynamic noise characteristics of open cavity structures under supersonic flow conditions. Detailed analyses were performed on both the flow field and acoustic field characteristics within the cavity, with comparative validation against experimental results demonstrating the accuracy of the numerical methodology. Furthermore, a novel noise suppression approach utilizing front-wall resonant cavity was proposed. The study revealed that properly designed front-wall resonant cavity in supersonic flow could effectively reduce the overall sound pressure level (OASPL), modal sound pressure level (SPL) amplitudes, and broadband SPL amplitudes within the cavity. This suppression method significantly improved the intense acoustic environment, effectively preventing vibration and acoustic fatigue failure in cavity structures and internal weapon systems. Critical design parameters including resonator depth (l), leading-edge lip thickness (t), and aperture size (d) were identified as key factors influencing noise suppression performance. For optimal engineering applications, comprehensive trade-offs between these parameters should be carefully considered during design optimization to achieve the maximum noise attenuation effect.
