Reactor With Cold Turning Plasma And Stream Forcing

A reactor for forming a plasma in a flowing fluid that includes a central rod belonging to a first electrode, an insulator, a tubular body belonging to a second electrode and defining a cylindrical space for the flow of the fluid between the tubular body and the insulator. The reactor further includes control disk having a front face linked to a downstream end of the central rod, and a permanent magnet juxtaposed against a back face of the control disk. One or more ribs are on a front face of the control disk according to a pattern in relief defining successive starting points for an electric arc distributed around the central axis of the reactor so as to generate electric arcs situated on a reaction cone and appearing to turn around the central axis.
