This work reviews the present position of and surveys future perspectives in the physics of
chaotic advection: the field that emerged three decades ago at the intersection of fluid …

Transport and mixing of scalar quantities in fluid flows is ubiquitous in industry and Nature.
While the more familiar turbulent flows promote efficient transport and mixing by their …

Several studies of the chaotic motion of fluid particles by two-dimensional time-periodic
flows or three-dimensional steady flows, called Lagrangian chaos, are first introduced …

Mixing under laminar flow conditions is key to a wide variety of industrial fluid systems of
size extending from micrometres to metres. Profound insight into three-dimensional laminar …

We study three-dimensional (3D) chaotic dynamics through an analysis of transport in a
granular flow in a half-full spherical tumbler rotated sequentially about two orthogonal axes …

Magnetic actuation of microscopic beads is a promising technique for enhancement and
manipulation of scalar transport in micro-fluidic systems. This implies laminar and essentially …

In this study, we explore the spectral properties of the distribution matrices of the mapping
method and its relation to the distributive mixing of passive scalars. The spectral (or …

This study employs three-dimensional particle-tracking velocimetry (3D-PTV) for
experimental investigation of the existence and properties of periodic lines in 3D lid-driven …

Heat transfer in fluid flows traditionally is examined in terms of temperature field and heat-
transfer coefficients at non-adiabatic walls. However, heat transfer may alternatively be …

Transport of passive tracers may be described through the spatio-temporal evolution of
Eulerian concentration distributions or via the geometrical composition of the Lagrangian …
