Be it avalanches, tornados, floods, or the air streams carrying an aircraft: Fluid flows are all around us. And sometimes, these flows are highly turbulent and powerful. “To be able to understand ...

The irregular, swirling motion of fluids we call turbulence can be found everywhere, from stirring in a teacup to currents in ...

Using the Frontier supercomputer at the Department of Energy's Oak Ridge National Laboratory, researchers from the Georgia Institute of Technology have performed the largest direct numerical ...

Introduction Have you ever seen a wind turbine? Wind turbines are large towers with blades on top that are spun by the wind. They are one source of clean, renewable energy. They use the movement from ...

This section was adapted from The Engine and the Atmosphere: An Introduction to Engineering by Z. Warhaft, Cambridge University Press, 1997. How many times a day do we turn on a faucet? Do it now.

The top row depicts a turbulent flow obtained from a direct numerical simulation (DNS) that fully resolves all scales of motion. The middle row represents incomplete observations in which small-scale ...
