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 …

Mixing is the operation by which a system evolves under stirring from one state of simplicity—
the initial segregation of the constituents—to another state of simplicity—their complete …

We study scalar mixing in heterogeneous conductivity fields, whose structural disorder
varies from weak to strong. A range of stretching regimes is observed, depending on the …

Chemical and biological reactions at fluid-solid interfaces are central to a broad range of
porous material applications and research. Pore-scale solute transport limitations can …

Consider a diffusion-free passive scalar θ being mixed by an incompressible flow u on the
torus ${\mathbb T}^ d $. Our aim is to study how well this scalar can be mixed under an …

In this study, we numerically investigate the evolution of two-dimensional mixing and heat
transfer enhancement within a two-rod stirring device. The fluid is heated by the walls, which …

We investigate the role of the correlation between a scalar quantity and the vorticity in two-
dimensional mixing at infinite Péclet number. We assess, using a diffusivity-independent …

This work develops an efficient and accurate optimization algorithm to study the optimal
mixing problem driven by boundary control of unsteady Stokes flows, based on 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 …

We study the relaxation of an initially segregated scalar mixture in a randomly stirred
medium, aiming at describing the overall concentration distribution of the mixture, its shape …
