Measurements are presented of the vortex shedding frequency from a pair of smooth parallel circular cylinders in both tandem and staggered arrangements for diameter ratios of 0.5, 1 and 2. No discontinuity was observed in the variation of the Strouhal number of the downstream cylinder with respect to the streamwise separation. For a pair of identical cylinders in tandem arrangement, the downstream body inhibited the vortex formation behind the upstream one up two diameters spacing. It was generally inferred that the Reynolds number and the turbulence characteristics of the free-stream flow as well as the cylinders aspect ratio are significant factors in the vortex shedding behavior. |
