Turbulence at Low Reynolds Numbers
Ziyue Yu, Xinyu Si, Lei Fang
Turbulence -- ubiquitous in nature and engineering alike [1-5] -- is traditionally viewed as an intrinsically inertial phenomenon, emerging only when the Reynolds number (Re), whic…

Manipulating the direction of turbulent energy flux via tensor geometry in a two-dimensional flow
Xinyu Si, Filippo De Lillo, Guido Boffetta +1
In turbulent flows, energy flux refers to the transfer of kinetic energy across different scales of motion, a concept that is a cornerstone of turbulence theory. The direction of n…
