Relevance of the Basset history term for Lagrangian particle dynamics
Julio Urizarna-Carasa, Daniel Ruprecht, Alexandra von Kameke +1
The movement of small but finite spherical particles in a fluid can be described by the Maxey-Riley equation (MRE) if they are too large to be considered passive tracers. The MRE c…
Lagrangian studies of coherent sets and heat transport in constant heat flux-driven turbulent Rayleigh-Bénard convection
Philipp P. Vieweg, Anna Klünker, Jörg Schumacher +1
We explore the mechanisms of heat transfer in a turbulent constant heat flux-driven Rayleigh-Bénard convection flow, which exhibits a hierarchy of flow structures from granules to…
Open-flow mixing and transfer operators
Anna Klünker, Kathrin Padberg-Gehle, Jean-Luc Thiffeault
We study finite-time mixing in time-periodic open flow systems. We describe the transport of densities in terms of a transfer operator, which is represented by the transition matri…
Evolutionary clustering of Lagrangian trajectories in turbulent Rayleigh-Bénard convection flows
Christiane Schneide, Philipp P. Vieweg, Jörg Schumacher +1
We explore the transport mechanisms of heat in two- and three-dimensional turbulent convection flows by means of the long-term evolution of Lagrangian coherent sets. They are obtai…
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…
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…
Probing turbulent superstructures in Rayleigh-Bénard convection by Lagrangian trajectory clusters
Christiane Schneide, Ambrish Pandey, Kathrin Padberg-Gehle +1
We analyze large-scale patterns in three-dimensional turbulent convection in a horizontally extended square convection cell by Lagrangian particle trajectories calculated in direct…
