Multiple states in turbulent large-aspect-ratio thermal convection: what determines the number of convection rolls?

Q Wang, R Verzicco, D Lohse, O Shishkina - Physical review letters, 2020 - APS
Wall-bounded turbulent flows can take different statistically stationary turbulent states, with
different transport properties, even for the very same values of the control parameters. What …
