ABSTRACT:
In the broader aspects of the invention there is provided an improved nozzle, an improved nozzle assembly and an improved method in which the improved nozzle comprises a protrusion having an distal end and a collar extending backward from the distal end. The collar is surface free of discontinuities. The outer end has an edge and an adjacent point at which the charge is concentrated. The protrusion has a fluid passage. The fluid passage is sealed from the collar surface. The fluid passage has an outlet adjacent the edge. A conductor is disposed in the protrusion. The conductor extends into the passage and is immersed in the fluid being disposed.
