Structure Functions and Intermittency for Coarsening Systems
Pradeep Kumar Yadav, Mahendra K. Verma, Sanjay Puri
In studies of turbulence, there has been extensive use of physical quantities such as {\it energy transfers} and {\it structure functions}. We examine whether these quantities can…
Kolmogorov Scaling for Total Energy and Cross Helicity in Magnetohydrodynamic Turbulence
Manthan Verma, Abhishek K. Jha, Mahendra K. Verma
The problem of scaling in isotropic magnetohydrodynamic (MHD) turbulence has remained unresolved, with competing predictions of (Kolmogorov) and (Iroshnikov-K…
Numerical Demonstration of Kolmogorov Scaling in Magnetohydrodynamic Turbulence
Manthan Verma, Abhishek K. Jha, Shashwat Nirgudkar +1
The two leading models of isotropic magnetohydrodynamic (MHD) turbulence have competing predictions: (Kolmogorov) and (Iroshnikov-Kraichnan) scalings. This pa…
Bursting of columnar structures in forced rotating turbulence
Arupjyoti Das, Manohar Sharma, Avishek Ranjan +1
In this study, we report intermittent bursting of cyclonic columnar structures in direct numerical simulations of forced rotating turbulence in a three-dimensional (3D) periodic bo…
Relative accuracy of turbulence simulations using pseudo-spectral and finite difference solvers
Akash Rodhiya, Shashwat Bhattacharya, Mahendra K Verma
For a single timestep, a spectral solver is known to be more accurate than its finite-difference counterpart. However, as we show in this paper, turbulence simulations using the tw…
Contrasting thermodynamic and hydrodynamic entropy
Mahendra K. Verma, Rodion Stepanov, Alexandre Delache
In this paper, using \textit{hydrodynamic entropy} we quantify the multiscale disorder in Euler and hydrodynamic turbulence. These examples illustrate that the hydrodynamic entropy…
Insights into the Energy Transfers in Hydrodynamic Turbulence Using Field-theoretic Tools
Mahendra K. Verma
Turbulent flows exhibit intriguing energy transfers. In this paper, we compute the renormalized viscosities, mode-to-mode energy transfers, energy fluxes, and shell-to-shell energy…
Cross helicity sign reversals in the dissipative scales of magnetohydrodynamic turbulence
V. Titov, R. Stepanov, N. Yokoi +2
We perform direct numerical simulations of magnetohydrodynamic (MHD) turbulence with kinetic energy and cross helicity injections at large scales. We observe that the cross helicit…
