Numerical Modeling of Wire Screens for Flow and Noise Control

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

“…Therefore, numerical modeling for porous fairing surfaces appears mandatory in order to reduce the computational costs. A numerical modeling of wire screens for flow and noise control was, for instance, proposed by Okolo et al [8] using a volume-averaged method implemented in an improved delayed detached-eddy simulation solver. Their approach introduces virtual screen porous regions in the computational domain, where sink correction terms are added in the Navier-Stokes momentum equations.…”

Numerical Simulations of a Landing Gear with Flow Through Fairings for Noise Mitigation

“…Most of the fairings considered in practice are usually made of perforated plates e.g. [4], but other alternative, such as wire meshes appear as a valuable option [5][6][7][8]. A dedicated program to study and categorize flow-through fairings for the mitigation of landing gear noise is currently under progress in the framework of the European Union Horizon 2020 research project INVENTOR (INnoVative dEsign of iNstalled airframe componenTs for aircraft nOise Reduction).…”
