Reconnection rate for the inhomogeneous resistivity petschek model
The reconnection rate for the canonical simplest case of steady-state two-dimensional symmetric reconnection in an incompressible plasma is found by matching of an outer Petschek solution and an internal diffusion region solution. The reconnection rate obtained naturally incorporates both Sweet-Parker and Petschek regimes, while the latter is possible only for a strongly localized resistivity.
