Characterization of separated flow over the boeing bump

The experimental progress in characterizing the flow separation downstream of the Boeing bump model is presented. Two-component particle image velocimetry was implemented to provide mean velocity and turbulence data in the region downstream of the bump apex. The experimental setup, including the incoming parameters of the upstream boundary layer and skin friction development, is documented comprehensibly. The measurement calibration and processing of the image data is described in detail. Initial observations of the vector fields include the development of the mean separation and reattachment points, as well as the characteristics of the turbulent wake. Embedded shear layer scaling is implemented to highlight the inviscid instability located in the inflection point of the mean velocity profile. Comparisons to a blindly conducted delayed detached eddy simulation is made to show its promising future, and current limitations. This work is meant to highlight the obvious features of the flow, and to announce the current state of the experimental campaign.
