Two scenarios for the development of patchy magnetic reconnection in current sheets above flare arcades. This work likens the MHD processes here to a "peristaltic pump", a concept well-known both in gastrointestinal tracts and in mechanical systems (the link shows an animated cartoon). This paper explores some of the side effects.
