摘要

Following earlier suggestions to replace the ensemble average used in the mean-field electrodynamics by an averaging over the azimuthal coordinate, we consider the basic coefficients in the turbulent electromotive force (EMF) as time-dependent functions. The well-known dynamo coefficients #x3B1; and #x3B7;T- both in the relevant tensorial formulations - are derived from one and the same turbulence field with maximal helicity so that in a local formulation the total turbulent EMF is described as a time series. The (kinematic) turbulence models have always the same intensity of #x2243; 100 ms#x2212;1and the number of the eddies in the unit length is varied. The EMF-coefficients #x3B1; and #x3B7;Tare evaluated within the limit of high (microscopic) conductivity.
