Simulations of astrophysical dynamos
Axel Brandenburg
Numerical aspects of dynamos in periodic domains are discussed. Modifications of the solutions by numerically motivated alterations of the equations are being reviewed using the ex…
How can vorticity be produced in irrotationally forced flows?
Fabio Del Sordo, Axel Brandenburg
A spherical hydrodynamical expansion flow can be described as the gradient of a potential. In that case no vorticity should be produced, but several additional mechanisms can drive…
Turbulent magnetic pressure instability in stratified turbulence
Koen Kemel, Axel Brandenburg, Nathan Kleeorin +1
A reduction of total mean turbulent pressure due to the presence of magnetic fields was previously shown to be a measurable effect in direct numerical simulations. However, in the…
Shear-driven instabilities in Hall-MHD plasmas
Cecilia Bejarano, Daniel Gómez, Axel Brandenburg
The large-scale dynamics of plasmas is well described within the framework of magnetohydrodynamics (MHD). However, whenever the ion density of the plasma becomes sufficiently low,…
Magnetic helicity fluxes in alpha Omega dynamos
Simon Candelaresi, Axel Brandenburg
In turbulent dynamos the production of large-scale magnetic fields is accompanied by a separation of magnetic helicity in scale. The large- and small-scale parts increase in magnit…
Kinetic helicity decay in linearly forced turbulence
Axel Brandenburg, Arakel Petrosyan
The decay of kinetic helicity is studied in numerical models of forced turbulence using either an externally imposed forcing function as an inhomogeneous term in the equations or,…
