Thermal convection in one, two, three and four dimensions
Ambrish Pandey, Harshit Tiwari, Katepalli R. Sreenivasan
We study by means of direct numerical simulations the influence of the dimensionality of convection on flow properties. We call attention to a few general principles from consideri…
Circulation Statistics in Rayleigh-Bénard Convection
Giovanni Saisse, Roshan J. Samuel, Luca Moriconi +2
Important statistical properties of velocity circulation in homogeneous isotropic turbulence (HIT) have been unveiled in recent years, raising the question of whether they persist,…
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 tim…
