1. A system for generating a plasma discharge in liquid, the system comprising:
a liquid inlet and a liquid outlet in fluid communication with an interior reactor space of a cylindrical liquid vessel having a central axis, the inlet and outlet both disposed near a top side of the liquid vessel and configured to generate a vortex liquid flow in the interior space of the liquid vessel; and
a high voltage electrode and a ground electrode spaced apart, the high voltage electrode disposed coaxially with the central axis of the cylindrical liquid vessel at a bottom side of the liquid vessel, and including a central solid cylindrical rod inserted at least partially into and coaxial with a cylindrically-symmetric bell-shaped electrode housing, the bell-shaped electrode housing including a gas channel disposed tangentially to the central solid rod along an interior wall of the bell-shaped electrode housing for gas injection into an interior electrode housing space of the bell-shaped electrode housing, the gas channel configured to generate a vortex gas flow within the interior electrode housing space around the central solid cylindrical rod.
