Abstract:The complex interactions present in the recompression and reattachment regions of the flowfield are shown to de-stabilize the turbulent structure organization. The mean structure statistics of all drag-altered flowfields demonstrate that the dominant organization present upstream is significantly weakened or lost due to passage through these regions. When the base bleed rate is sufficient to inhibit the formation of the primary recirculation region, the structures evident upstream survive into the developing wake region.
