Abstract
AbstractUsing direct numerical simulations, we study the properties of turbulent superstructures in thermal convection in a large aspect ratio square cell. We estimate the characteristic length scale of superstructures using spatial auto‐correlation functions and two‐dimensional power spectra, and observe that the typical length scale increases weakly with increasing Prandtl number. We also find that the Prandtl number dependence of heat and momentum transport are similar to those observed in small aspect ratio systems. (© 2017 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
