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 …

Turbulent gas motions are observed in the intracluster medium (ICM). The ICM is density-
stratified, with the gas density being highest at the centre of the cluster and decreasing …

The gas motions in the intracluster medium (ICM) are governed by turbulence. However,
since the ICM has a radial profile with the centre being denser than the outskirts, ICM …

In this paper, using a shell model, we simulate highly turbulent stably stratified flow for weak
to moderate stratification at unitary Prandtl number. We investigate the energy spectra and …

There is considerable evidence for widespread subsonic turbulence in galaxy clusters, most
notably from Hitomi. Turbulence is often invoked to offset radiative losses in cluster cores …

A randomly stirred model, akin to the one used by DeDominicis and Martin for
homogeneous isotropic turbulence, is introduced to study Bolgiano–Obukhov scaling in fully …

Understanding the behavior of the kinetic energy spectrum and flux in two-dimensional (2D)
turbulent thermal convection remains a challenge. In this paper, using high-resolution direct …

Budgets of turbulent kinetic energy (TKE) and turbulent potential energy (TPE) at different
scales $\ell $ in sheared, stably stratified turbulence are analysed using a filtering approach …

The seminal Bolgiano–Obukhov (BO) theory established the fundamental framework for
turbulent mixing and energy transfer in stably stratified fluids. However, the presence of BO …

Accelerated glacier melt and the loss of perennial snowfields have been associated with
increased warming in polar regions, at rates up to four times faster than the rest of the world …
