A Lagrangian analysis of coherent structures in 2D annular Rayleigh-Bénard convection
Luis Álamo, Jezabel Curbelo, Kathrin Padberg-Gehle
Convective instabilities are studied from a Lagrangian perspective in order to gain new insights into how the resulting global, long-lived coherent flow structures organize themsel…
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…
Role of critical points of the skin friction field in formation of plumes in thermal convection
Vinodh Bandaru, Anastasiya Kolchinskaya, Kathrin Padberg-Gehle +1
The dynamics in the thin boundary layers of temperature and velocity is the key to a deeper understanding of turbulent transport of heat and momentum in thermal convection. The vel…
