Taming Turbulence: Seeking to Make Complex Simulations a Breeze
Researchers used state-of-the-art supercomputers to examine how turbulence plays out over long periods of time when its motions include shear flow, a component that normally dies away very quickly.

Researchers at the University of Wisconsin-Madison and the University of Texas used state-of-the-art supercomputers to examine how turbulence plays out over long periods of time when its motions include shear flow, a component that normally dies away very quickly.
Looking at the system in detail, the team observed that shear flow is amplified over time and exerts greater influence than was previously known.
This research allowed the team to dramatically improve existing models for how shear-flow turbulence changes in different systems.
Said University of Wisconsin-Madison researcher Adrian Fraser, "The end result is a simple model that predicts results that are very consistent with the massive simulations we performed."
