Thermal convection in 1, 2, 3 and 4 dimensions
Ambrish Pandey, Harshit Tiwari, Katepalli R. Sreenivasan
The authors use direct numerical simulations to investigate how the dimensionality of thermal convection (from 1D to 4D) influences flow characteristics, focusing on the time neede…
Influence of plume activity on thermal convection in a rectangular cell
Ambrish Pandey, Jörg Schumacher, Matteo Parsani +1
We present three-dimensional direct numerical simulations of turbulent Rayleigh-Bénard convection in a closed rectangular box whose width and length are 0.8 and 2.4 ti…
Scale-resolved turbulent Prandtl number for Rayleigh-Bénard convection at
Shashwat Bhattacharya, Dmitry Krasnov, Ambrish Pandey +2
We present a framework to calculate the scale-resolved turbulent Prandtl number for the well-mixed and highly inertial bulk of a turbulent Rayleigh-Bénard mesoscale convect…
Transient and steady convection in two dimensions
Ambrish Pandey, Katepalli R. Sreenivasan
We simulate thermal convection in a two-dimensional square box using the no-slip condition on all boundaries, and isothermal bottom and top walls and adiabatic sidewalls. We choose…
Turbulent mesoscale convection in the Boussinesq limit and beyond
Shadab Alam, Dmitry Krasnov, Ambrish Pandey +4
Mesoscale convection covers an intermediate scale range between small-scale turbulence and the global organization of the convection flow. It is often characterized by an order of…
