Abstract
Abstract A system for affecting the flow of a fluid medium relative to an object including a first plurality of surface deviations disposed on the surface of the object in contact with the fluid medium. The deviations are arranged into at least one predetermined pattern which includes a plurality of radially extending deviation sets. A second plurality of surface deviations are disposed on at least one of the first plurality of surface deviations. The second plurality of surface deviations are arranged in a second predetermined pattern which includes a plurality of radially extending deviation sets. The deviations may be indentations or projections from the surface.
