Abstract

The generation of large-scale vortices in the helical turbulence is usually called the hydrodynamical alpha-effect (-effect) [1]. The equation for the mean field has the same form as appropriate α-effect equation in the mean-field MHD:
$${\partial _t}\Omega + \alpha cur\Omega = v\Delta \Omega $$
