Fluid flow technology takes a cue from fast-swimming sharks

COLUMBUS, Ohio -- A study of airflow in pipes may help solve a mystery concerning the ears of fast-swimming sharks. The results could also lead to new audio technologies, according to an engineer at Ohio State University.

Konrad Koeltzsch, a postdoctoral researcher in chemical engineering and the Alexander von Humboldt Fellow at Ohio State, and his colleagues investigated grooves in sharkskin called riblets.

Koeltzsch began to study sharkskin while he was a postdoctoral researcher at the Dresden University of Technology in Germany. He worked with Albrecht Dinkelacker, a German researcher who pioneered the study of riblets, and Dresden professor Roger Grundmann. The three published their results in a recent issue of the journal Experiments in Fluids.

Some 20 years ago, engineers found that lining a pipe with riblet-like grooves could speed flow through a pipe by as much as 10 percent.

The very idea that a textured surface could speed fluid flow appears counterintuitive at first, Koeltzsch said. "We normally think that smooth surfaces cause the least drag," he explained. A fundamental point in fluid mechanics is that rough surfaces increase drag, and sharkskin is considered rough. If such a rough surface reduces dr
