Abstract: The transient processes of a turbulent large-scale convective circulation (LSC) in a cubic cell are investigated using large-eddy simulations for Rayleigh number $\Ray=10^8$ and Prandtl number $\Pran=0.7$. For the first time, we have explicitly shown… read more here.

DOI: 10.1080/23744731.2018.1556054
Abstract: Two classes of nonuniform three-layer models were developed to examine the transient flows driven by a localized heat source. The buoyancy combination coefficient () was proposed, and the buoyancy of the near-ceiling layer was assumed… read more here.
