FIELD: technology of hydro-dynamic cavitation; forming cavitation jets for treatment of surfaces submerged in liquid, for example, ship's hulls and water-development works for removal of fouling, corrosion crust and chemical and/or mechanical deposition.
SUBSTANCE: proposed method includes delivery of liquid under pressure through passage of nozzle-cavitator and organization of vortex motion of liquid jet in passage of nozzle-cavitator and/or immediately before it. Liquid may be heated to boiling point before admitting it to passage of nozzle-cavitator. It is good practice to subject liquid to action of magnetic field before admitting it to passage and/or directly inside passage of nozzle-cavitator. Proposed method ensures laminirization of jet flow, reduces hydrodynamic resistance and increases velocity of liquid with no use of chemical modifying agents.
EFFECT: enhanced efficiency; reduced power requirements.
