Pattern formation by turbulent cascades

XM de Wit, M Fruchart, T Khain, F Toschi, V Vitelli - Nature, 2024 - nature.com
Fully developed turbulence is a universal and scale-invariant chaotic state characterized by
an energy cascade from large to small scales at which the cascade is eventually arrested by …

Oscillations in aggregation-shattering processes
