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 …

The goal of the present study is threefold:(i) to demonstrate the two-dimensional nature of
the elasto-inertial instability in elasto-inertial turbulence (EIT),(ii) to identify the role of the …

Turbulent fluctuations induce the common phenomenon known as clustering in the spatial
arrangement of small inertial particles transported by the fluid. Particles spread non …

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 …

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 …

Direct numerical simulations (DNS) of turbulent fronts spreading into an irrotational flow
region are used to analyse the turbulent entrainment mechanism for viscoelastic fluids. The …

Maximum drag reduction (MDR), the asymptotic upper limit of reduction in turbulent friction
drag by polymer additives, is the most important unsolved problem in viscoelastic …

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 …
