Scientific paper

The paper presents two two-dimensional MHD models with anomalous resistivity which simulate an externally driven magnetic reconnection. Computer results have shown the formation of X-shaped slow shocks which satisfy the Rankine-Hugoniot shock conditions; they also showed that plasmas entering into the magnetic island through the X-type neutral points are moderately accelerated along the magnetic island boundaries. In the open-ended case, the plasma acceleration is intensified, and strong jet streams are generated on the downstream side of the slow shocks. The jet streams concentrate preferentially along the plasma sheet boundaries which is attributed to sharp pressure gradients along the magnetic field lines due to slow shocks whose fronts obliquely intersect the field lines; finally, an examination of the energy conversion rate has shown that the externally driven magnetic reconnection acts as a powerful magnetic energy converter.
