DAFE - Fundamental and Experimental Aerodynamics department
The Fundamental and Experimental Aerodynamics Department (DAFE) has acquired a worldwide expertise in advanced optical measurement methods matching the wind tunnel operating conditions (hardware, software, methodology ...).
To study complex aerodynamic flows with the aim of improving the understanding of these phenomena, finding out about unexpected behaviors and participating in the definition of systems that have to operate in extreme conditions. To build databases for validating theoretical models and calculation codes.
Areas of expertise
In priority, the work covers:
- separated turbulent flows, the formation and development of vortexes,
- shock phenomena, in particular, shock interferences and shock wave/boundary layer interactions,
- turbulence, unsteady effects and instabilities in free flows
Particle Image Velocimetry technique
For PIV (Particle Image Velocimetry) technique applied in our windtunnels, GMT is using the GPU technique and FOLKI software to speed-up data processing, developped by DTIM and DAFE.
