The alpha-effect in rotating convection: size matters

  • DAVID W. HUGHES (a1) and FAUSTO CATTANEO (a2)

Abstract

The results of numerical simulations of convection in a rotating layer are used to compute the α-effect of mean-field electrodynamics. The computations are carried out for different system sizes. It is found that the outcomes can depend critically on the system size, and that physically meaningful results can only be obtained if the system size is large compared with the typical eddy size.
