Abstract

This paper investigates the performance of different turbulence models for simulatinthe aeroacoustic field generated by turbulent flow. The acoustic field is calculated by solving thlinearized Euler equations (LEE), while the acoustic source is obtained by solving the incompressible Navier-Stokes equations. Three different turbulence models are adopted for the flow simulation: the large eddy simulation (LES), the delayed detached-eddy simulation (DDESand unsteady Reynolds Averaged Navier-Stokes equations (URANS). The acoustic sources arcalculated on a flow grid and then transferred and interpolated onto an acoustic grid, enablinthe acoustic computation of the far field with a reasonable computational cost. We present thacoustic sources calculated using different turbulence models. Furthermore, we compare thsound pressure level (SPL) spectra of different turbulence models with the experimental data.
