Using HLRS’s Hawk supercomputer, University of Stuttgart scientists have for the first time produced high-resolution simulation data characterizing the transition from low to high Reynolds numbers in ...

Small-scale velocity fluctuations in turbulent boundary layers are often coupled with the largerscale motions. Studying the nature and extent of this scale interaction allows for a statistically ...

Anyone who has flown in an airplane knows about turbulence, or when the flow of a fluid — in this case, the flow of air over the wings — becomes chaotic and unstable. For more than a century, the ...

The precise dynamics of breakdown in pipe transition is a century-old unresolved problem in fluid mechanics. We demonstrate that the abruptness and mysteriousness attributed to the Osborne Reynolds ...

Turbulence modeling is one of the main sources of uncertainty in CFD simulations of technical flows. This is not surprising, as turbulence is the most complex phenomenon in classical physics.

Turbulence is an omnipresent phenomenon - and one of the great mysteries of physics. A research team has now succeeded in generating realistic storm turbulence in the wind tunnel of the Center for ...
