Vortex shedding flow behind a slowly rotating circular cylinder

Vortex shedding flow behind a slowly rotating circular cylinder

This paper investigates flow past a rotating circular cylinder at 3600⩽Re⩽5000 and α⩽2.5. The flow parameter α is the circumferential speed at the cylinder surface normalized by the free-stream velocity of the uniform cross-flow. With particle image velocimetry (PIV), vortex shedding from the cylind...

Zusammenfassung:This paper investigates flow past a rotating circular cylinder at 3600⩽Re⩽5000 and α⩽2.5. The flow parameter α is the circumferential speed at the cylinder surface normalized by the free-stream velocity of the uniform cross-flow. With particle image velocimetry (PIV), vortex shedding from the cylinder is clearly observed at α
