In physical systems, a reduction in dimensionality often leads to exciting new phenomena.
Here we discuss the novel effects arising from the consideration of fluid turbulence confined …

We review selected recent developments on the role of chaotic advection in the dynamics of
nonpassive particles. This topic is fundamental to understanding or controlling transport of …

Turbulent flows have been used for millennia to mix solutes; a familiar example is stirring
cream into coffee. However, many energy, environmental, and industrial processes rely on …

Mixing of shear‐thinning fluids with yield stress is investigated in a three‐dimensional (3‐D)
flow both in experiments and in simulations. Experiments are conducted in a stirred tank …

Understanding mixing and transport of passive scalars in active fluids is important to many
natural (eg, algal blooms) and industrial (eg, biofuel, vaccine production) processes. Here …

The exponential decay of the variance of a passive scalar released in a homogeneous
random two-dimensional flow is examined. Two classes of flows are considered: short …

Co-flow microfluidics, in addition to its applications in droplet generation, has gained
popularity for use with miscible solvent systems (continuous microfluidics). By leveraging the …

Chaotic mixing in a closed vessel is studied experimentally and numerically in different two-
dimensional (2D) flow configurations. For a purely hyperbolic phase space, it is well known …

Forced two-dimensional turbulence lives on the balance between the energy input and two
dissipative mechanisms, viscosity and linear friction, resulting in a double cascade of energy …

We report a laser-induced fluorescence (LIF) experimental method that is able to quantify
dye concentration in a laminar three-dimensional flow. The geometry of interest is a stirred …
