The small-scale statistics of homogeneous isotropic turbulence of dilute polymer solutions is investigated by means of direct numerical simulations of a simplified viscoelastic fluid model. It is found that polymers only partially suppress the turbulent cascade below the Lumley scale, leaving a remnant energy flux even for large elasticity. As a consequence, fluid acceleration in viscoelastic flows is reduced with respect to Newtonian turbulence, whereas its rescaled probability density is left…

Dispersed Fibers Change the Classical Energy Budget of Turbulence via Nonlocal Transfer.

The backreaction of dispersed rigid fibers to turbulence is analyzed by means of a state-of-the-art fully coupled immersed boundary method and provides a link between two apparently separated realms: the one of porous media and theOne of suspension dynamics.

Scaling Relations in Elastic Turbulence.

The scaling relations between the exponents of the power-law decays of kinetic and elastic energies, pressure, as well as torque fluctuations in elastic turbulence (ET) agree well with the exponent values obtained experimentally and numerically in the ET regime of a viscoelastic fluid in different flow geometries.

Spectral energy transfer in a viscoelastic homogeneous isotropic turbulence

Energy dynamics in elastoinertial turbulence is investigated by performing different direct numerical simulations of stationary, homogeneous isotropic turbulence for the range of Weissenberg numbers

Isotropic Turbulence with Coupled Microstructures. I: Visco-Elastic Turbulence

This chapter is devoted to the dynamics of isotropic turbulence in dilute polymer solutions. Governing equations associated to the very popular FENE-P rheological model are exhaustively discussed.

Drag enhancement and drag reduction in viscoelastic flow

Creeping flow of polymeric fluid without inertia exhibits elastic instabilities and elastic turbulence accompanied by drag enhancement due to elastic stress produced by flow-stretched polymers.

Energy spectra in elasto-inertial turbulence

Direct numerical simulations of statistically steady homogeneous isotropic turbulence in viscoelastic fluids described by the FENE-P model are presented. Emphasis is given to large polymer relaxation

The Effect of Polymers

Long-chain polymers usually possess a high degree of flexibility and, in their basic state, coil up to an approximately spherical shape. In a turbulent flow, the polymers become stretched and some of

Multifractal statistics of Lagrangian velocity and acceleration in turbulence.

The statistical properties of velocity and acceleration fields along the trajectories of fluid particles transported by a fully developed turbulent flow are investigated by means of high resolution direct numerical simulations and are compared with predictions of the multifractal formalism.
