Scalings of heat transport and energy spectra of turbulent Rayleigh-Benard convection in a large-aspect-ratio box

Arnab K. De, Vinayak Eswaran, Pankaj K. Mishra

Direct Numerical Simulations of turbulent convection in a large aspect-ratio box are carried out in the range of Rayleigh number $7\times 10^4\le Ra\le 2\times 10^6$ at Prandtl…
