METHOD FOR HYDRODYNAMIC PROCESSING A SURFACE AND DEVICE FOR CARRYING OUT SAID METHOD

摘要

The inventive method consists in acting upon the area of the processed surface by at least two cavitating pressure water jets, said action being carried out in such a way that the cavitating jets cross each other. The inventive device comprises at least two nozzles. A distance L between the longitudinal axis of the nozzles is selected according to a relation 25 tg( alpha /2) </= L/D PHI </=60 tg( alpha /2), wherein alpha is the angle of divergence of a cavitating jet, d PHI is a nozzle diameter. Said invention makes it possible to increase the processing performance, improve the processing uniformity for the entire surface, increase the concentration and uniformity of cavitating bubbles in the processed area and to reduce operation pressure.
