Disentangling intermittent flow structure contributions to anomalous scaling and multifractality in turbulence
Ritwik Mukherjee, Siddhartha Mukherjee
Intermittency in turbulence manifests as intense vortices and sharp peaks of dissipation. Causing the breakdown of Kolmogorov's simple self-similar theory, it leads to anomalous sc…
Turbulent flows are not uniformly multifractal
Siddhartha Mukherjee, Sugan D. Murugan, Ritwik Mukherjee +1
The Frisch-Parisi multifractal formalism remains the most compelling rationalisation for anomalous scaling in fully developed turbulence. We now show that this formalism can be ada…
Geometric characterization of vortex lines in turbulence
Saumav Kapoor, Rama Govindarajan, Siddhartha Mukherjee
Vorticity in turbulent flows is often organized into complex geometries that influence the dynamics. We use a relatively novel approach to describe these geometries: that of obtain…
Intermittency, fluctuations and maximal chaos in an emergent universal state of active turbulence
Siddhartha Mukherjee, Rahul K. Singh, Martin James +1
A hydrodynamic model of active, low Reynolds number suspensions, shows the emergence of an asymptotic state with a universal spectral scaling and non-Gaussian (intermittent) fluctu…
Lagrangian Manifestation of Anomalies in Active Turbulence
Rahul K. Singh, Siddhartha Mukherjee, Samriddhi Sankar Ray
We show that Lagrangian measurements in active turbulence bear imprints of turbulent and anomalous streaky hydrodynamics leading to a self-selection of persistent trajectories - Le…
Anomalous diffusion and Lévy walks distinguish active from inertial turbulence
Siddhartha Mukherjee, Rahul K. Singh, Martin James +1
Bacterial swarms display intriguing dynamical states like active turbulence. Using a hydrodynamic model we now show that such dense active suspensions manifest super-diffusion, via…
