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 . 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).
