Turbulent MHD transport coefficients

Previous calculations of turbulent magnetohydrodynamic (MHD) eddy viscosity and anomalous resistivity are reviewed. Emphasis is laid on a new approach to fully developed turbulence proposed by Canuto and Dubovikov, containing both systematic and heuristic elements for the ultraviolet (UV) and infrar...
