On two-dimensional magnetohydrodynamic turbulence
It is shown that two-dimensional MHD turbulence is in certain respects closer to threedimensional than to two-dimensional hydrodynamic turbulence. A second-order closure indicates that: (i) a t zero viscosity and magnetic diffusivity, a singularity appears a t a finite time; (ii) there is an energy cascade to small scales and an inverse cascade of squared magnetic potential, in agreement with a...
متن کاملMagnetic reconnection in two-dimensional magnetohydrodynamic turbulence.
Systematic analysis of numerical simulations of two-dimensional magnetohydrodynamic turbulence reveals the presence of a large number of X-type neutral points where magnetic reconnection occurs. We examine the statistical properties of this ensemble of reconnection events that are spontaneously generated by turbulence. The associated reconnection rates are distributed over a wide range of value...
متن کاملBroken ergodicity in two-dimensional homogeneous magnetohydrodynamic turbulence
Two-dimensional (2-D) homogeneous magnetohydrodynamic (MHD) turbulence has many of the same qualitative features as three-dimensional (3-D) homogeneous MHD turbulence. These features include several ideal invariants, along with the phenomenon of broken ergodicity. Broken ergodicity appears when certain modes act like random variables with mean values that are large compared to their standard de...
