Anisotropization of quasistatic magnetohydrodynamic turbulence with an increasing magnetic field: Transition from three to two dimensions

Abstract

A systematic description of turbulence behavior in response to the impact of external forces is one of the important outstanding problems of fluid dynamics. We study the process of turbulence anisotropization in quasi-static magnetohydrodynamic flows with an increasing magnetic field using quasi-normal scale elimination analytical theory and direct numerical simulations. The transition from isotropic turbulence at zero field to two-dimensional turbulence at strong field is investigated. Intermediate states and critical parameters of this transition are identified.
