ABSTRACT :

The main thread of this research project is the computational fluid dynamics (CFD), dedicated to the aeroacoustics applied to aeronautics and aerospace fields. The final objective of this program is to improve our knowledge in order to develop efficient CFD software to reduce the environmental impact of aircraft, helicopters, or rockets. With the aim to improve the physical models in CFD solver to help design, the analysis, understanding and high-fidelity predictions of compressible turbulent flows are the key points of these research activities. Aeroacoustics problems are by definition time dependent. Consequently, these works focus on the use of the Large-Eddy Simulation (LES) methodology to solve both turbulent flow and acoustics fields in complex geometries. Moreover, as most of the flows encountered are characterized by high Reynolds numbers, the use of High-Performance Computing (HPC) is also mandatory to reduce the restitution time. The topics presented in this research project are the development of high-order numerical methods, the adaptive mesh refinement, the turbulence modeling for boundary conditions, and the analysis of noise source mechanisms.
