Circular Cylinder
When circular cylinders are moved in still water, it is known that fluctuating lift exhibits nonrecursive characteristics even if the cylinder is repeatedly towed or swung under the same conditions. In this study, the cylinder is operated near a wall in towed or swung motion to investigate the effects of interaction with the wall on the nonrecursive characteristics of fluctuating lift. The effects of the interaction were evaluated by standard deviation of ensembly collected lift data at each towed distances or swung angles. The results obtained by this study will be applied to the development of manipulator arms operated in water where the effects of mechanical vibrations are insignificant in comparison of those of fluctuating fluid forces associated with vortex formation and the wall interaction.
