Evolving turbulence and magnetic fields in galaxy clusters
Kandaswamy Subramanian, Anvar Shukurov, Nils Erland L. Haugen
We discuss, using simple analytical models and MHD simulations, the origin and parameters of turbulence and magnetic fields in galaxy clusters. Three physically distinct regimes ca…
Nonhelical turbulent dynamos: shocks and shear
A. Brandenburg, N. E. L. Haugen, A. J. Mee
Small scale turbulent dynamo action in compressible transonic turbulence is discussed. It is shown that the critical value of the magnetic Reynolds number displays a bimodal behavi…
The problem of small and large scale fields in the solar dynamo
A. Brandenburg, N. E. L. Haugen, P. J. Käpylä +1
Three closely related stumbling blocks of solar mean field dynamo theory are discussed: how dominant are the small scale fields, how is the alpha effect quenched, and whether magne…
Shearing and embedding box simulations of the magnetorotational instability
A. Brandenburg, B. Dintrans, N. E. L. Haugen
Two different computational approaches to the magnetorotational instability (MRI) are pursued: the shearing box approach which is suited for local simulations and the embedding box…
Mach number dependence of the onset of dynamo action
Nils Erland L. Haugen, Axel Brandenburg, Antony J. Mee
The effect of compressibility on the onset of nonhelical turbulent dynamo action is investigated using both direct simulations as well as simulations with shock-capturing viscositi…
Inertial range scaling in numerical turbulence with hyperviscosity
Nils Erland L. Haugen, Axel Brandenburg
Numerical turbulence with hyperviscosity is studied and compared with direct simulations using ordinary viscosity and data from wind tunnel experiments. It is shown that the inerti…
