Correlation of internal flow structure with heat transfer efficiency in turbulent Rayleigh-Bénard convection
Ao Xu, Xin Chen, Feng Wang +1
To understand how internal flow structures manifest themselves in the global heat transfer, we study the correlation between different flow modes and the instantaneous Nusselt numb…

Tristable flow states and reversal of the large-scale circulation in two-dimensional circular convection cells
Ao Xu, Xin Chen, Heng-Dong Xi
We present a numerical study of the flow states and reversals of the large-scale circulation (LSC) in a two-dimensional circular Rayleigh-Bénard cell. Long-time direct numerical si…
