The network of interactions among fluid elements and coherent structures gives rise to the
incredibly rich dynamics of vortical flows. These interactions can be described with the use …

The detection of compartments and dead zones as well as the estimation of the mixing
efficiency in stirred tanks are of vital interest for a variety of biochemical and chemical …

Connectivity is a fundamental structural feature of a network that determines the outcome of
any dynamics that happens on top of it. However, an analytical approach to obtain …

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 …

The dispersion and mixing of passive particles in a turbulent channel flow are investigated
by means of a network-based representation of their motion. We employ direct numerical …

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 matrix of a …

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 …

We study the transition to turbulence in a flat plate boundary layer by means of visibility
analysis of velocity time-series extracted across the flow domain. By taking into account the …

The basin-wide surface transport of tracers such as heat, nutrients and plastic in the North
Atlantic Ocean is organized into large-scale flow structures such as the Western Boundary …

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 …
