The Kolmogorov flow (k-flow) is generated by a stationary sinusoidal force that varies in
space. This flow is rather academic since generating such a periodic forcing in an …

We show that turbulent dynamics that arise in simulations of the three-dimensional Navier-
Stokes equations in a triply periodic domain under sinusoidal forcing can be described as …

We consider turbulence in a stratified 'Kolmogorov'flow, driven by horizontal shear in the
form of sinusoidal body forcing in the presence of an imposed background linear stable …

In this paper, we study pseudospectral bounds for the linearized operator of the Navier‐
Stokes equations around the 3D Kolmogorov flow. Using the pseudospectral bound and the …

By extracting unstable invariant solutions directly from body-forced three-dimensional
turbulence, we study the dynamical processes at play when the forcing is large scale and …

This paper aims to investigate the nonlinear transition to turbulence in generalized 3D
Kolmogorov flow. The difference between this and classical Kolmogorov flow is that the …

Self-organized large-scale flow structures occur in a wide range of turbulent flows. Yet, their
emergence, dynamics, and interplay with small-scale turbulence are not well understood …

A three dimensional Kolmogorov problem with extended forcing term for Navier-Stokes
equations is considered in the extended periodic domain. The Galerkin {Fourier method is …

Preferential concentration is thought to play a key role in promoting particle growth, which is
crucial to processes such as warm rain formation in clouds, planet formation, and industrial …

Self-organising processes occurring in isotropic turbulence and homogeneous
magnetohydrodynamic (MHD) turbulence are investigated in relation to the stability of …
