Turbulent flows are characterized by the non-linear cascades of energy and other inviscid
invariants across a huge range of scales, from where they are injected to where they are …

We briefly review helicity dynamics, inverse and bidirectional cascades in fluid and
magnetohydrodynamic (MHD) turbulence, with an emphasis on the latter. The energy of a …

We present numerical evidence of how three-dimensionalization occurs at small scale in
rotating turbulence with Beltrami () forcing, creating helical flow. The Zeman scale at which …

Helicity, which is defined as the scalar product of velocity and vorticity,, consistent with
recent measurements by Koprov, Koprov, Ponomarev & Chkhetiani (Dokl. Phys., vol. 50 …

Analyzing a large database of high-resolution three-dimensional direct numerical
simulations of decaying rotating stratified flows, we show that anomalous mixing and …

The conventional approach to the turbulent energy cascade, based on Richardson-
Kolmogorov phenomenology, ignores the topology of emerging vortices, which is related to …

A numerical study of decaying stably stratified flows is performed. Relatively high
stratification (Froude number≈ 10− 2–10− 1) and moderate Reynolds (Re) numbers (Re≈ …

Processes of Benard cell origination and disintegration in air are studied experimentally. It is
shown that temperature gradients cause a Benard cell. Our data confirm the main scenarios …

The paper presents a closed system of three-dimensional hydrodynamic equations of
averaged motion, intended for modeling spiral turbulence in a rotating astrophysical disk …

Helicity is inherent in many circulating motions and structures in the atmospheric boundary
layer (ABL), where it is continuously reproduced due to the combined action of the Earth's …
