The present article aims at highlighting the strengths and weaknesses of the so-called
spectral-like optimized (explicit central) finite-difference schemes, when the latter are used …

The computation of flow-induced noise at low Mach numbers usually relies on a two-step
hybrid methodolgy. In the first step, an incompressible fluid dynamics simulation (CFD) is …

Future air traffic regulations are going to further limit the noise and pollutant emissions of
aero engines in a way that can only be met by the comprehensive migration towards lean …

A two-way coupling on unstructured meshes between a flow and a high-order acoustic
solvers for jet noise prediction is considered. The flow simulation aims at generating …
