Kraichnan like model of turbulence with stratification
Heikki Arponen
A generalization to the Kraichnan gaussian, white noise in time model of turbulent velocity field is proposed. The generalization is designed to take into account the effects of st…
Steady state existence of passive vector fields under the Kraichnan model
Heikki Arponen
The steady state existence problem for Kraichnan advected passive vector models is considered for isotropic and anisotropic initial values in arbitrary dimension. The model include…
Anomalous scaling and anisotropy in models of passively advected vector fields
Heikki Arponen
The small and large scale problem of various passive vector models with anisotropic forcing is considered by solving exactly the equation for the pair correlation function. Emphasi…
Dynamo effect in the Kraichnan magnetohydrodynamic turbulence
Heikki Arponen, Peter Horvai
The existence of a dynamo effect in a simplified magnetohydrodynamic model of turbulence is considered when the magnetic Prandtl number approaches zero or infinity. The magnetic fi…
