Magnetohydrodynamic turbulent flows driven by random mechanical and electromagnetic external forces of zero helicities are investigated by means of direct numerical simulations. It is shown that despite the absence of helicities in the forcing, the system is attracted to self-organized helical states that exhibit laminar behaviour despite the large value of the Reynolds numbers examined. We demonstrate that the correlation time of the external forces is controlling the time spent on these…

Low-dimensional models of the transition to turbulence

The transition to turbulence in shear flows such as pressure driven pipe flow or plane Couette flow presents an interesting theoretical problem: how do we understand the existence of chaos when the

On-off intermittency and hard turbulence in the flow of fluid in the magnetic field.

An analysis of experiments in which various modes of mercury flow in a constant external magnetic field were observed provides evidence of the chaotic nature of the observed flow modes despite the relative weakness of high-frequency harmonics in comparison to low-frequency ones.

Spectral properties of homogeneous magnetohydrodynamic turbulence

Magnetohydrodynamics (MHD) is the study of how an electrically-conducting fluid interacts with a magnetic field. Many of the constituents of the universe possess a magnetic field and MHD has




Implications of certain applications of turbulence theory to two-dimensional turbulence and magnetohydrodynamic flow are discussed. It is shown that the use of the Navier-Stokes equation (NSE) for

Using massive numerical simulations, it is shown that small-scale structures and their intermittency properties differ according to whether helicity is present or not, in particular with respect to the emergence of Beltrami core vortices that are laminar helical vertical updraft vortsices.

Low-frequency 1/f fluctuations in hydrodynamic and magnetohydrodynamic turbulence.

It is observed that the 1/f range is present in the largest available wavelength mode for the magnetohydrodynamic simulations with and without a background magnetic field and it is not observed (or is less clear) for the hydrodynamic case.

Helicity dynamics in stratified turbulence in the absence of forcing.

It is discovered that the decay rate of energy for stratified helical flows is much slower than for stratifying nonhelical flows and can be considered with a phenomenological model in a way similar to what is done for unstratified rotating flows.
