We consider the problem of an inextensible but flexible fiber advected by a steady chaotic flow, and ask the simple question of whether the fiber can spontaneously knot itself. Using a one-dimensional Cosserat model, a simple local viscous drag model and discrete contact forces, we explore the probability of finding knots at any given time when the fiber is interacting with the ABC class of flows. The bending rigidity is shown to have a marginal effect compared to that of increasing the fiber…

Spontaneous knotting of an agitated string
Based on the observation that long, stiff strings tend to form a coiled structure when confined, a simple model is proposed to describe the knot formation based on random “braid moves” of the string end that can qualitatively account for the observed distribution of knots and dependence on agitation time and string length.
Dynamics and topology of a flexible chain: knots in steady shear flow
We use numerical simulations of a bead–spring model chain to investigate the evolution of the conformations of long and flexible elastic fibers in a steady shear flow. In particular, for rather open
3D conformation of a flexible fiber in a turbulent flow
A growing number of studies is devoted to anisotropic particles in turbulent flows. In most cases, the particles are assumed to be rigid and their deformations are neglected. We present an adaptation
Simulation of the motion of flexible fibers in viscous fluid flow
A model for flexible fibers in viscous fluid flow is proposed, and its predictions compared with experiments found in the literature. The incompressible three-dimensional Navier–Stokes equations are
The Helicity of a Knotted Vortex Filament
The helicity H associated with a knotted vortex filament is considered. The filament is first constructed starting from a circular tube, in three stages involving injection of (integer) twist,
Flexible fiber in a turbulent flow: a macroscopic polymer.
A model for the transition from rigid to flexible regimes as the intensity of turbulence is increased or the elastic energy of the fiber is decreased is proposed and it is demonstrated that the conformations of flexible fibers in a turbulent flow are analog to conformation of flexible polymers in a good solvent.
Untangling the mechanics and topology in the frictional response of long overhand elastic knots.
An analytical model based on the nonlinear theory of thin elastic rods is developed to describe how the physical and topological parameters of the knot set the tensile force required for equilibrium.
The energy spectrum of knots and links
KNOTTED and linked structures arise in such disparate fields as plasma physics, polymer physics, molecular biology and cosmic string theory. It is important to be able to characterize and classify
Dynamic patterns and self-knotting of a driven hanging chain.
It is found experimentally that instabilities occur in tonguelike bands of parameter space, to swinging or rotating pendular motion, or to chaotic states, as well as within the well-known resonance tongues.
Dynamics of a long chain in turbulent flows: impact of vortices
How a long bead–spring chain, immersed in a homogeneous isotropic turbulent flow, preferentially samples vortical flow structures is shown and explained.
