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…

Biologically generated turbulent energy cascade in shear flow depends on tensor geometry
Xinyu Si, Lei Fang
It has been proposed that biologically generated turbulence plays an important role in material transport and ocean mixing. Both experimental and numerical studies have reported ev…
