In three-dimensional hydrodynamic turbulence forced at large length scales, a constant
energy flux Π u flows from large scales to intermediate scales, and then to small scales. It is …

We present an overview of the statistical properties of turbulence in two-dimensional (2D)
fluids. After a brief recapitulation of well-known results for statistically homogeneous and …

Non-Newtonian fluids have a viscosity that varies with applied stress. Elastoviscoplastic
fluids, the elastic, viscous and plastic properties of which are interconnected in a non-trivial …

Direct numerical simulations (DNS) of spatially evolving turbulent planar jets of viscoelastic
fluids described by the FENE-P model, such as those consisting of a Newtonian fluid solvent …

We use direct numerical simulations to study homogeneous and isotropic turbulent flows of
dilute polymer solutions at high Reynolds and Deborah numbers. We find that for small …

Liquid velocity fluctuations and energy spectra in three-dimensional buoyancy-driven
bubbly flows Page 1 J. Fluid Mech. (2020), vol. 884, R6, doi:10.1017/jfm.2019.991 journals.cambridge.org/rapids …

We report 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). The …

Elastic turbulence is a chaotic regime that emerges in polymer solutions at low Reynolds
numbers. A common way to ensure stability in numerical simulations of polymer solutions is …

Elastic turbulence is the chaotic fluid motion resulting from elastic instabilities due to the
addition of polymers in small concentrations at very small Reynolds (Re) numbers. Our …

Direct numerical simulations of statistically steady homogeneous isotropic turbulence in
viscoelastic fluids described by the FENE-P model, such as those laden with polymers, are …
