Description
Turbulence is a natural state of high Reynolds flows and is ubiquitous in
astrophysical
systems. In most cases turbulence is externally driven, but one also
expects the
outflows induced by reconnection to get turbulent. High resolution
numerical
resolution reconnection simulations in 3D also show the transition to
the turbulent
state. Therefore it is essential to understand how turbulence affects
magnetic
reconnection. I shall be discussing the model of fast turbulent
reconnection suggested
in Lazarian & Vishniac 1999, its numerical and observational testing
and its more
recent extensions to the processes of reconnection in relativistic fluids
and partially
ionized gas. I shall show simulations obtained with different numerical
schemes that
support the theoretical expectations and discuss simulations of self-
sustained
turbulent reconnection. Finally, I shall touch upon the vast
astrophysical applications
of the turbulent reconnection theory.
