IRT visualization of boundarylayer transition... The wind tunnel is well adapted to study complex flow phenomena (three dimensional boundarylayer, flow separation, jet interaction, wakes. Boundarylayer transition
Boundarylayer rake... Pressure rake for boundarylayer study. Static boundarylayer pressure rake: to analyze boundarylayer profile. This rake could be design and manufacture on request (static or motorized boundarylayer pressure rake)
ONERA thus measured itself against the international state of the art in terms of precision and performance of modern CFD methods for unsteady aerodynamics:** fine multiscale turbulence, higher-order geometric representations, HPC (High Performance Computing) efficiency, shock / boundarylayer interaction problems
Manoeuvring in such conditions might increase the shock, causing the rise of pressure gradient and the separation of the boundarylayer. A zone of recirculation appears downstream from the shock
