Magnetohydrodynamic Turbulence

 

Magnetohydrodynamics (MHD) describe physical systems where a fluid is coupled to a magnetic field. MHD turbulence is present in many areas of physics, ranging from industrial applications such as liquid metal technology to nuclear fusion and plasma physics, geo-, astro- and solar physics, and even cosmology.

  • Chaotic behaviour of Eulerian MHD turbulence 

    Ho, Richard DJG
    We study the chaos of a turbulent conducting fluid using direct numerical simulation in the Eulerian frame. We predict that the Lyapunov exponent, which measures the exponential separation of initially close solutions of ...

  • Fully-resolved array of simulations investigating the influence of the magnetic Prandtl number 

    McKay, Mairi E; Berera, Arjun; Ho, Richard DJG
    This dataset is for a paper which is currently in submission. We explore the effect of the magnetic Prandtl number Pr_M on energy and dissipation in fully-resolved direct numerical simulations of steady-state, ...

  • Comparison of forcing functions in magnetohydrodynamics 

    McKay, Mairi E; Linkmann, Moritz F; Clark, Daniel; Chalupa, Adam A; Berera, Arjun
    Results are presented of direct numerical simulations of incompressible, homogeneous magnetohydrodynamic turbulence without a mean magnetic field, subject to different kinetic forcing functions commonly used in the literature. ...

  • Nonuniversality and finite dissipation in magnetohydrodynamic turbulence 

    Linkmann, Moritz F; Berera, Arjun; McComb, W David; McKay, Mairi E
    This dataset contains the results of the study discussed in the paper 'Nonuniversality and finite dissipation in decaying magnetohydrodynamic turbulence': "A model equation for the Reynolds number dependence of the ...
