Transient flows and reorientations of large-scale convection in a cubic cell
Andrei Vasiliev, Peter Frick, Abhishek Kumar +3
The transient processes of a turbulent large-scale convective circulation (LSC) in a cubic cell are investigated using large-eddy simulations for Rayleigh number $\Ray=10^8$ and Pr…
Statistical features of rapidly rotating decaying turbulence: enstrophy and energy spectra, and coherent structures
Manohar K. Sharma, Abhishek Kumar, Mahendra K. Verma +1
In this paper we investigate the properties of rapidly rotating decaying turbulence using numerical simulations and phenomenological modelling. We find that as the turbulent flow e…
Complexity of viscous dissipation in turbulent thermal convection
Shashwat Bhattacharya, Ambrish Pandey, Abhishek Kumar +1
Using direct numerical simulations of turbulent thermal convection for Rayleigh number () between and and unit Prandtl number, we derive scaling relation…
