We analyze large-scale patterns in three-dimensional turbulent convection in a horizontally
extended square convection cell by Lagrangian particle trajectories calculated in direct …

In Rayleigh–Bénard convection (RBC) for fluids with Prandtl number Pr≳ 1, rotation beyond
a critical (small) rotation rate is known to cause a sudden enhancement of heat transfer …

Using curvature and torsion to describe Lagrangian trajectories gives a full description of
these as well as an insight into small and large time scales as temporal derivatives up to …

Background rotation causes different flow structures and heat transfer efficiencies in
Rayleigh–Bénard convection. Three main regimes are known: rotation unaffected, rotation …

Geophysical flows are often turbulent and subject to rotation. This rotation modifies the
structure of turbulence and is thereby expected to sensibly affect its Lagrangian properties …

The Lagrangian perspective, describing a flow from the trajectories of fluid tracers, isa
natural framework for studying dispersion phenomena in turbulent flows. In wall …

The angle of directional change of tracer trajectories in rotating Rayleigh-Bénard convection
is studied as a function of the time increment τ between two instants of time along the …

Thermally driven turbulent convection has been initially studied by Henri Bénard and Lord
Rayleigh more than a century ago. In 1900, Henri Bénard observed that the flow motion is …

Rayleigh–Bénard convection, a confined fluid layer heated from below and cooled from
above, is the classical system to study thermally driven flows. It is mathematically well …
