Simulations of the anisotropic kinetic and magnetic alpha effects
A. Brandenburg, K. Subramanian
The validity of a closure called the minimal tau approximation (MTA), is tested in the context of dynamo theory, wherein triple correlations are assumed to provide relaxation of th…

Kinetic and magnetic alpha effects in nonlinear dynamo theory
Sharanya Sur, Kandaswamy Subramanian, Axel Brandenburg
The backreaction of the Lorentz force on the alpha-effect is studied in the limit of small magnetic and fluid Reynolds numbers, using the first order smoothing approximation (FOSA)…
