Abstract

The separation of a turbulent boundary layer developing over a flat plate at nearly-zero pressure gradient was experimentally studied in this work in the Large Water-Tunnel Braunschweig. The reported measurements were conducted via Temperature-Sensitive Paint and Lagrangian Particle Tracking by Shake-The-Box in the region downstream of a backward-facing ramp, which induced a turbulent separation bubble. The examined Reynolds numbers, based on the ramp location, were in the range 1.2 to 2.7 million.
