Turbulent jet noise simulation and propagation using a 3rd order MUSCL/CD scheme on unstructured grid and Ffowcs-williams hawkings

Abstract

The noise generation by a turbulent high speed jet is simulated using Large Eddy Simulation (LES) and a newly implemented MUSCL/CD 3rd order numerical scheme. The acoustic wave propagation in the far-field is performed using a permeable formulation Ffowcs Williams-Hawkings (FW-H) approach, available in the STAR-CCM+ code. The flow-field results and the predicted sound pressure levels are both in good agreement with experiments. The predicted sound pressure levels using LES are within a 1–2 dB deviation for all measured observer locations.
