On the fully coupled dynamics of flexible fibres dispersed in modulated turbulence

  title={On the fully coupled dynamics of flexible fibres dispersed in modulated turbulence},
  author={Stefano Olivieri and Andrea Mazzino and Marco E. Rosti},
The present work investigates the mechanical behaviour of finite-size, elastic and inertial fibres freely moving in a homogeneous and isotropic turbulent flow at moderate Reynolds number. Four-way coupled, direct numerical simulations, based on a finite difference discretisation and the immersed boundary method, are performed to mutually couple the dynamics of fibres and fluid turbulence, allowing to account for the backreaction of the dispersed phase to the carrier flow. An extensive parametric study… 


Turbulence in a network of rigid fibers
The effect of a network of fixed rigid fibers on fluid flow is investigated by means of three-dimensional direct numerical simulations using an immersed boundary method for the fluid-structure
Flexible Fiber Reveals the Two-Point Statistical Properties of Turbulence.
A phenomenological theory is presented to describe the interaction between the fiber elasticity and the turbulent flow and leads to the identification of two distinct regimes of flapping, which are validated against direct numerical simulations fully resolving the fiber dynamics.
Numerical modelling of long flexible fibers in homogeneous isotropic turbulence
Abstract.We numerically investigated the transport, deformation and buckling events of an isolated elastic fiber in Taylor-Green vortices and studied the dynamics of long filaments in homogeneous
Universal features of the shape of elastic fibres in shear flow
Abstract We present a numerical study of the dynamics of an elastic fibre in a shear flow at low Reynolds number, and seek to understand several aspects of the fibre's motion using the equations for
Orientation, distribution, and deformation of inertial flexible fibers in turbulent channel flow
In this paper, we investigate the dynamics of flexible fibers in turbulent channel flow. Fibers are longer than the Kolmogorov length scale of the carrier flow, and their velocity relative to the
Numerical study of filament suspensions at finite inertia
We present a numerical study on the rheology of semi-dilute and concentrated filament suspensions of different bending stiffness and Reynolds number, with the immersed boundary method used to couple
On the orientation of stiff fibres suspended in turbulent flow in a planar contraction
The influence of turbulence on the orientation state of a dilute density matched suspension of stiff fibres at high Reynolds number in a planar contraction is investigated. High-speed imaging and
Dynamics and fragmentation of small inextensible fibres in turbulence
The fragmentation of small, brittle, flexible, inextensible fibres is investigated in a fully developed, homogeneous, isotropic turbulent flow and it is indeed shown that the statistics of break-up is fully determined by the probability distribution of Lagrangian fluid velocity gradients.
Flowing fibers as a proxy of turbulence statistics
The flapping states of a flexible fiber fully coupled to a three-dimensional turbulent flow are investigated via state-of-the-art numerical methods. Two distinct flapping regimes are predicted by the
Homogeneous isotropic turbulence in dilute polymers
The modification of the turbulent cascade by polymeric additives is addressed by direct numerical simulations of homogeneous isotropic turbulence of a FENE-P fluid. According to the appropriate form
