Growth rate of the initial magnetic energy in isotropic velocity field with non-Gaussian distribution

Growth rate of the initial magnetic energy in isotropic velocity field with non-Gaussian distribution

We propose a method for including the effects of non-Gaussian velocity field distribution in the estimation of growth rate of the magnetic energy in a random flow with finite memory time. The method allows a reduction to the Gaussian case that was investigates earlier. For illustration we consider t...

Zusammenfassung:We propose a method for including the effects of non-Gaussian velocity field distribution in the estimation of growth rate of the magnetic energy in a random flow with finite memory time. The method allows a reduction to the Gaussian case that was investigates earlier. For illustration we consider the multivariate Laplace distribution and compare it against the Gaussian one.
