Collective variables between large-scale states in turbulent convection
Priyanka Maity, Andreas Bittracher, Péter Koltai +1
The dynamics in a confined turbulent convection flow is dominated by multiple long-lived macroscopic circulation states, which are visited subsequently by the system in a Markov-ty…
Large-scale flow in a cubic Rayleigh-Bénard cell: Long-term turbulence statistics and Markovianity of macrostate transitions
Priyanka Maity, Péter Koltai, Jörg Schumacher
We investigate the large-scale circulation (LSC) in a turbulent Rayleigh-Bénard convection flow in a cubic closed convection cell by means of direct numerical simulations at a Rayl…
Lagrangian coherent sets in turbulent Rayleigh-Bénard convection
Christiane Schneide, Martin Stahn, Ambrish Pandey +4
Coherent circulation rolls and their relevance for the turbulent heat transfer in a two-dimensional Rayleigh--Bénard convection model are analyzed. The flow is in a closed cell of…
Diffusion maps embedding and transition matrix analysis of the large-scale flow structure in turbulent Rayleigh--Bénard convection
Péter Koltai, Stephan Weiss
By utilizing diffusion maps embedding and transition matrix analysis we investigate sparse temperature measurement time-series data from Rayleigh--Bénard convection experiments in…
