Nazarenko O. Hydrodynamic emitting systems with by axessymmetrical localized area of cavitation nature

The thesis is devoted to studying the process of oscillations generation by fluid submerged jets, inleaking over a plain barrier. Given is the physical explanation of localized cavitation area generation and forming, which area periodically blasts with the content into environment. A transcendental dispersion equation obtained correlates the frequency with that system’s geometrical and hydrodynamic parameters. For the first time a theoretical calculation effected exposes the excessive pressure maximum value, at which the cavitation bubble blasts; established is the fact of vortex’ damping prior to content blowout. For the first time suggested is the proposal of using the cavitation bubbles’ collapsing energy for nano-coating applying onto metals surfaces.
