Computational Fluid Dynamics and Aeroacoustics

Mission

To develop numerical simulation methods and software in aerodynamics and energetics and manage all the aeroacoustic activities in order to meet the requirements for the prediction and optimization of aircraft performance.

Areas of expertise

• Developing numerical methods in aerodynamics and energetics
• Software engineering
• Numerical simulation
• Experimentation and measuring in aeroacoustics

The applications cover combustion in engines and internal and external flows for all types of aircraft, fixed or rotating wing, low to hypersonic speeds, and space launchers. The purpose of the aeroacoustic studies is to reduce noise caused by the aerodynamics or the propulsion.

Activities

• Large Eddy Simulation (LES)
• Direct numerical simulation (DNS)
• AMR platform and rapid algorithms in unsteady combustion
• Helicopter noise
• Numerical aero-acoustics of fans
• Location of acoustic sources
• Turbofan noise
• Launch vehicle acoustic environment
• Acoustic propagation
• Numerical simulation in aeroacoustics

Projects

• CEDRE: software for flow computation in energetics
• elsA: Aerodynamics Simulation Software Package
• MSDH project : MSD and CEDRE software packages (with ONERA/DEFA)
• ASSM Project: solid-propellant propulsion
• Cocomat - Coupling mechanical and aerothermal codes
• Cassiopée: a set of services for CFD pre- and post-processing
