Scientific paper

The paper reports on the results of plasma jet and shock formation during the current loop coalescence in solar flares. It is shown by a theoretical model based on the ideal MHD equation that the spiral, two-sided plasma jet can be explosively driven by the plasma rotational motion induced during the two current loop coalescence process. The maximum velocity of the jet can exceed the Alfven velocity, depending on the plasma beta ratio. The acceleration time getting to the maximum jet velocity is quite short and less that 1 s. The rebound following the plasma collapse driven by magnetic pinch effect can strongly induce super-Alfvenic flow.
