jspargo1,

You are correct. The term used to describe the oscillation of a cylinder subjected to the movement of water or air, is vortex shedding. The circular twists assist in dampening the movement of the cylinder. The same features are often seen on smokestacks.

There is a name for the feature, but I cannot recall it.
