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…

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…
