Salient and smooth edge ramps inducing turbulent boundary layer separation: Flow characterization for control perspective
Comptes Rendus. Mécanique, Volume 342 (2014) no. 6-7, pp. 356-362.

Turbulent boundary layer separation induced by a salient ramp and a smooth-edge one are characterized. Upstream from the separation point, the momentum thickness Reynolds number Reθ3500. Pressure distribution and gradient pressure distribution are analyzed on the overall model. Upstream from the ramp, boundary layer is characterized using hot-wire anemometry. Recirculation zone and unsteady behavior of separation point are evaluated using a PIV system. The shear layer roll-up and vortex shedding times scales obtained with cross hot-wire anemometry show good agreements with the literature. This study is a step toward the development of a robust control strategy undertaken in the frame of the ANR SePaCode project (2011–2014).
