Numerical Wire Mesh Model for the Simulation of Noise-Reduction Devices

This study deals with the development of a numerical wire mesh screen model for unsteady simulation aeroacoustic configurations. Such devices are indeed growing interest practical applications because they potentially lead to significant noise-reduction effects. Numerical simulations including screens therefore major optimize their possible location and properties, as well get better understanding involved physical phenomena. On basis several finely resolved (direct large-eddy simulation) flow through an isolated sample, is proposed calibrated. An application method tandem cylinder test case then performed different locations porosities. The introduction in observed some cases reduction radiated noise, by up 8 dB.
