Statistics of the inverse-cascade regime in two-dimensional magnetohydrodynamic turbulence
Debarghya Banerjee, Rahul Pandit
We present a detailed direct numerical simulation of statistically steady, homogeneous, isotropic, two-dimensional magnetohydrodynamic (2D MHD) turbulence. Our study concentrates o…
Transition from dissipative to conservative dynamics in equations of hydrodynamics
Debarghya Banerjee, Samriddhi Sankar Ray
We show, by using direct numerical simulations and theory, how, by increasing the order of dissipativity () in equations of hydrodynamics, there is a transition from a dissipati…
Multiscaling in Hall-Magnetohydrodynamic Turbulence: Insights from a Shell Model
Debarghya Banerjee, Samriddhi Sankar Ray, Ganapati Sahoo +1
We show that a shell-model version of the three-dimensional Hall-magnetohydrodynamic (3D Hall-MHD) equations provides a natural theoretical model for investigating the multiscaling…
Real-space Manifestations of Bottlenecks in Turbulence Spectra
Uriel Frisch, Samriddhi Sankar Ray, Ganapati Sahoo +2
An energy-spectrum bottleneck, a bump in the turbulence spectrum between the inertial and dissipation ranges, is shown to occur in the non-turbulent, one-dimensional, hyperviscous…
