Topological chaos has emerged as a powerful tool to investigate fluid mixing. While this theory can guarantee a lower bound on the stretching rate of certain material lines, it does not indicate what fraction of the fluid actually participates in this minimally mandated mixing. Indeed, the area in which effective mixing takes place depends on physical parameters such as the Reynolds number. To help clarify this dependency, we numerically simulate the effects of a batch stirring device on a 2D…

Chaotic advection in a recirculating flow: Effect of a fluid-flexible-solid interaction.

The present work is on laminar recirculating flow-induced deformation as well as motion of a neutrally buoyant flexible elliptical solid, resulting in Lagrangian chaos in a two-dimensional lid-driven

Topological Entropy of Surface Braids and Maximally Efficient Mixing

The deep connections between braids and dynamics by way of the Nielsen-Thurston classification theorem have led to a wide range of practical applications. Braids have been used to detect coherent

Braids in the heart: global measures of mixing for cardiovascular flows

It is proposed and demonstrated that braids of random and sparse particle trajectories provide an intuitive, global and practical description of cardiovascular flows and exposed the flow pattern in an experimental healthy left ventricle model as a highly effective blood mixer at the topological level.



Topological chaos in inviscid and viscous mixers

A fast technique for computing the velocity field for either inviscid, irrotational or highly viscous flow, which enables accurate numerical simulation of dye advection and finds close agreement with Boyland et al., irrespective of whether the fluid is modelled as Inviscid or viscous.

Topological fluid mechanics of stirring

A new approach to regular and chaotic fluid advection is presented that utilizes the Thurston–Nielsen classification theorem. The prototypical two-dimensional problem of stirring by a finite number

Quantification of the performance of chaotic micromixers on the basis of finite time Lyapunov exponents

Chaotic micromixers such as the staggered herringbone mixer developed by Stroock et al. allow efficient mixing of fluids even at low Reynolds number by repeated stretching and folding of the fluid

Influence of the Reynolds number on chaotic mixing in a spatially periodic micromixer and its characterization using dynamical system techniques

A micromixer is a key component of various microfluidic systems, such as microreactors and μ-total analysis systems. One important strategy for passive mixer design is to generate chaotic advection

Topological mixing with ghost rods.

The ghost rods framework provides a new technique for quantifying chaos and gives insight into the mechanisms that produce chaos and mixing.

We discuss mixing and transport in three-dimensional, steady, Navier–Stokes flows with the no-slip condition at the boundaries. The advective flux is related to the dynamics of the Navier–Stokes

Topological chaos, braiding and bifurcation of almost-cyclic sets.

It is made the case that a topological analysis based on spatiotemporal braiding of almost-cyclic sets can be used for analyzing chaos in fluid flows and develops a connection between set-oriented statistical methods and topological methods, which promises to be an important analysis tool in the study of complex systems.

Simulation of topological chaos in laminar flows.

The immersed boundary method is used for numerical simulation of Stokes-flow mixing driven by stirrers moving in a such way that trajectories of the stirrers form a "braid" in the augmented phase space.
