Interaction of an off-surface cylinder with separated flow from a bluff body leading edge

•Phase locking between cylinder and bubble shedding while flapping not affected.•Cylinder pressure gradient eliminates separation bubble.•Cylinder shedding Strouhal number is reduced due to increased blockage from bubble.•When cylinder near the wall bubble flapping modes dominate over shedding modes...
