A combined wall pressure/velocity analysis of the wake of a disk located in the vicinity of a flat wall is presented in this paper. One gap ratio only is selected. In this situation, the footprint of the flow unsteadiness on the magnitude of the wall fluctuating pressure is significant while the natural vortex shedding properties of the wake are only slightly altered. Spatio-temporal velocity and...
The unsteady wake of a flat disk (diameter D) located at a distance of H from a flat plate has been experimentally investigated at a Reynolds number ReD = 1.3 × 105. Tests have been performed for a range of gap ratio (H/D), spanning from 0.3 to 1.75. The leading edge of the flat plate is either streamlined (elliptical) or blunt (square). These configurations have...
