Anisotropy of third-order structure functions in MHD turbulence
Andrea Verdini, Roland Grappin, Petr Hellinger +2
The measure of the third-order structure function, Y, is employed in the solar wind to compute the cascade rate of turbulence. In the absence of a mean field B0=0, Y is expected to…
Three-dimensional Iroshnikov-Kraichnan turbulence in a mean magnetic field
Roland Grappin, Wolf-Christian Müller, Andrea Verdini +1
Forced, weak MHD turbulence with guide field is shown to adopt different regimes, depending on the magnetic excess of the large forced scales. When the magnetic excess is large eno…
Role of helicities for the dynamics of turbulent magnetic fields
Wolf-Christian Müller, Shiva Kumar. Malapaka
Investigations of the inverse cascade of magnetic helicity are conducted with pseudospectral, three-dimensional direct numerical simulations of forced and decaying incompressible m…
Fluctuation dynamo amplified by intermittent shear bursts in convectively driven magnetohydrodynamic turbulence
J. Pratt, A. Busse, W. -C. Mueller
Intermittent large-scale high-shear flows are found to occur frequently and spontaneously in direct numerical simulations of statistically stationary turbulent Boussinesq magnetohy…
Non Axi-symmetric Anisotropy of Solar Wind Turbulence
A. J. Turner, G. Gogoberidze, S. C. Chapman +2
A key prediction of turbulence theories is frame-invariance, and in magnetohydrodynamic (MHD) turbulence, axisymmetry of fluctuations with respect to the background magnetic field.…
Universality of the Small-Scale Dynamo Mechanism
R. Moll, J. Pietarila Graham, J. Pratt +3
We quantify possible differences between turbulent dynamo action in the Sun and the dynamo action studied in idealized simulations. For this purpose we compare Fourier-space shell-…
