000014004 520__ $$2eng$$aThe flow development over stationary and oscillating circular cylinders with two distinct end conditions has been investigated experimentally for 2100 ≤ ReD ≤ 7000. The end conditions employed correspond to a free surface and a free end. For both the stationary and oscillating cylinder, near the free surface the wake vortices are oriented parallel to the cylinder axis. Circulation is preserved in this region with vortices terminating at the free surface. Near the free end the vortices cannot end abruptly in the fluid, hence, they must either incline towards the cylinder and maintain a direct connection to the free end (observed for 2S type shedding pattern) or they must form halfloop connections with adjacent vortices of the opposite sign (observed for the 2P type shedding pattern). The apparent changes in vortex dynamics due to differing end conditions may significantly influence the unsteady loading characteristics.
