Abstract
Axially fed fluid is sheared during long residence time in a radial workspace between counter-rotating coaxial disk-shaped centrifugal impellers. Gases evolve in the fractal turbulence of a shear layer, which is forced between laminar boundary layers, and an axial suction pump axially extracts evolved noncondensables and volatiles through cores of radial vortices in the shear layer. Cavitation due to shear between the impellers kills pathogens by shock waves, microjets, OH radicals, and nearby UV light pulses. Oppositely charged electrodes bounding the workspace cause electroporesis and electrohydraulic cavitation. The electrodes are counter-rotating ridged armatures of disk dynamos, forming a dynamic capacitor having audio frequency pulsed electric fields. Electrode erosion by arcing is prevented by shear between the electrodes.
