Sheared Helical Turbulence and the Helicity Constraint in Large-Scale Dynamosity conservation. Because of shear, the time scale needed to reach an equipartition-strength large scale field is shortened proportionally to the ratio of the resulting toroidal to poloidal large scale fields.

Small- and Large-Scale Dynamo Action in Simple Forced Flows (mean) field and measure the associated α-effect. We find that a significant non-zero α-effect can exist, indicating possible dynamo action on scales larger than the velocity scale, when sometimes no dynamo action exists at the velocity scale itself. Flows exist which are not small-scale dynamos, yet may be large-scale dynamos.

Detaillierung der Handlungsfelder, broken by introducing a scale separation in the flow, or by letting develop a small non-symmetric perturbation which can be either kinetic and magnetic, or only magnetic [.]. We present cases where a long term magnetic field produced by dynamo action saturates. Implications of our results to VK sodium experiments are discussed.

To get closer to the real MHD problems, new designs of experimental devices and new numerical codes are needed in order to achieve greater Rm, study the turbulent characteristics, the nonlinear saturation regime and the influence of large-scale flow configuration and boundaries.

Preliminary Measurement of the Turbulent Magnetic Diffusivity in Three Dimensionsn energy are required in order to suppress the effective turbulent diffusion. In order to elucidate this question we performed numerical calculations based on the full, incompressible MHD equations, that allow us to measure the effective magnetic diffusivity for different values of the large-scale magnetic field strength.
