Year: 2024
Type: conference-paper
Abstract: In order to more accurately simulate the acoustic properties of the fluid in the cavity, this paper uses four different turbulence models, LES, Spalart-Allmaras/LES, Realizable/LES, model, to simulate and calculate the simple cavity, combined with the acoustic experimental data carried out on the cavity model, and found that the simulated experimental values of pulsating pressure from the SST-k-/LES model and the Spalart-Allmaras/LES model have a better agreement with the simulated experimental values of the cavity pulsation pressure, and the calculated sound pressure spectra obtained from the SST-k-/LES model are the closest to the experimental values.
