Helical shell models for MHD turbulence

Based on the helical decomposition of both the magnetic and the velocity fields, a helical shell model for MHD turbulence is introduced. It is used to study the influence of the forcing helicity on the onset of dynamo. It is shown that the well-known GOY shell model is not well adapted for such a st...
