Non-Boussinesq convection at low Prandtl numbers relevant to the Sun
Ambrish Pandey, Jörg Schumacher, Katepalli R. Sreenivasan
Convection in the Sun occurs at Rayleigh numbers, , as high as , molecular Prandtl numbers, , as low as , under conditions that are far from satisfying th…
Echo State Network for two-dimensional turbulent moist Rayleigh-Bénard convection
Florian Heyder, Jörg Schumacher
Recurrent neural networks are machine learning algorithms which are suited well to predict time series. Echo state networks are one specific implementation of such neural networks…
Lagrangian heat transport in turbulent three-dimensional convection
Philipp P. Vieweg, Christiane Schneide, Kathrin Padberg-Gehle +1
Spatial regions that do not mix effectively with their surroundings and thus contribute less to the heat transport in fully turbulent three-dimensional Rayleigh-Bénard flows are id…
Fractal iso-level sets in high-Reynolds-number scalar turbulence
Kartik P. Iyer, Jörg Schumacher, Katepalli R. Sreenivasan +1
We study the fractal scaling of iso-levels sets of a passive scalar mixed by three-dimensional homogeneous and isotropic turbulence at high Reynolds numbers. The Schmidt number is…
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…
