An investigation of the dynamo instability close to the threshold produced by an ABC forced flow is presented. We focus on the on-off intermittency behavior of the dynamo and the countereffect of theâ€¦ (More)

We consider the induction of a magnetic field in flows of an electrically conducting fluid at low magnetic Prandtl number and large kinetic Reynolds number. Using the separation between the magneticâ€¦ (More)

The paper considers dynamo action in steady fluid flows having a catâ€™s eye stream line topology. The flows considered are two-dimensional, depending on x and y only, but have all three components ofâ€¦ (More)

This paper considers magnetic field generation by a fluid flow in a system referred to as the Archontis dynamo: a steady nonlinear magnetohydrodynamic (MHD) state is driven by a prescribed bodyâ€¦ (More)
