Reduction of Triadic Interactions Suppresses Intermittency and Anomalous Dissipation in Turbulence
Anikat Kankaria, Ritwik Mukherjee, Sugan Durai Murugan +2
We investigate how the defining statistical features of three-dimensional turbulence respond to systematic reductions of the Fourier-space triadic interaction network. Using direct…

Geometric Intermittency in Turbulence
Ritwik Mukherjee, Siddhartha Mukherjee, I. V. Kolokolov +3
Equal-time scaling exponents in fully developed turbulence typically exhibit non anomalous scaling in the inverse cascade of two-dimensional (2D) turbulence and anomalous scaling i…

Intermittent fluctuations determine the nature of chaos in turbulence
Aikya Banerjee, Ritwik Mukherjee, Sugan Durai Murugan +2
We adapt recent ideas for many-body chaos in nonlinear, Hamiltonian fluids [Murugan \textit{et al.}, Phys. Rev. Lett. 127, 124501 (2021)] to revisit the question of the Reynolds nu…
