Computation of kinematic and magnetic $\alpha$-effect and eddy diffusivity tensors by Padé approximation

Sílvio M. A. Gama, Roman Chertovskih, Vladislav Zheligovsky

We present examples of Padé approximation of the $\alpha$-effect and eddy viscosity/diffusivity tensors in various flows. Expressions for the tensors derived in the framework of the sta…
