Dynamics of reversals and condensates in 2D Kolmogorov flows
Pankaj Kumar Mishra, Johann Herault, Stephan Fauve +1
We present direct numerical simulations of the different two-dimensional flow regimes generated by a constant spatially periodic forcing balanced by viscous dissipation and large s…
Sweeping effect and Taylor's hypothesis via correlation function
Mahendra K. Verma, Abhishek Kumar
We performed high-resolution numerical simulations of hydrodynamic turbulence with and without mean velocity (), and demonstrate the sweeping effect. For , the vel…
Similarities between 2D and 3D convection for large Prandtl number
Ambrish Pandey, Mahendra K. Verma, Anando G. Chatterjee +1
Using direct numerical simulations of Rayleigh-Bénard convection (RBC), we perform a comparative study of the spectra and fluxes of energy and entropy, and the scaling of large-sca…
Flow reversals in turbulent convection with free-slip walls
Mahendra K. Verma, Siddhesh C. Ambhire, Ambrish Pandey
We perform numerical simulations of turbulent convection for infinite Prandtl number with free-slip walls, and study the dynamics of flow reversals. We show interesting correlation…
Energy Spectrum of Buoyancy-Driven Turbulence
Abhishek Kumar, Anando G. Chatterjee, Mahendra K. Verma
Using high-resolution direct numerical simulation and arguments based on the kinetic energy flux , we demonstrate that for stably stratified flows, the kinetic energy spectrum…
Energy transfers in dynamos with small magnetic Prandtl numbers
Rohit Kumar, Mahendra K. Verma, Ravi Samtaney
We perform numerical simulation of dynamo with magnetic Prandtl number on grid, and compute the energy fluxes and the shell-to-shell energy transfers. T…
