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 …

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 …

A class of unsteady two-and three-dimensional velocity fields for which the associated stable
and unstable manifolds of the Lagrangian trajectories are explicitly known is introduced …

Abstract The three-dimensional (3D) flow due to AC electroosmotic (ACEO) forcing on an
array of interdigitated symmetric electrodes in micro-channels is experimentally analyzed …

ACEO-induced vortices have been used to manipulate fluids and particles for chemical and
biochemical analysis in microscale systems. In such applications, a pressure-driven …

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 …

A Lagrangian coherent structure (LCS) in a nonautonomous flow can be viewed as an open
dynamical system, from which there is time-dependent escape or entry. A difficulty with this …

Laminar mixing by the inline-mixing principle is a key to many industrial fluids-engineering
systems of size extending from micrometers to meters. However, insight into fundamental …

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

Heat transfer in essence is the transport of thermal energy along certain paths in a similar
way as fluid motion is the transport of fluid parcels along fluid paths. This similarity admits …
