FIELD: between interface at hydrodynamics and hydrobiology; turbomachines of hydroelectric stations, pumped-storage hydroelectric stations, pumping plants and other hydraulic machines and plants. SUBSTANCE: process of forming cavities is transferred from solid and/or liquid and/or gaseous nuclei to gaseous nuclei, from plankton cavitation nuclei (plankton organisms) to air bubbles in particular by forming gaseous cavitation nuclei, air bubbles in particular in addition to available nuclei. Innovation of invention consists in forming new gaseous cavitation nuclei, air bubbles in particular by passing the gas through porous material or/and through screen (cellular) material. EFFECT: extended range of control of number and sizes of gaseous cavitation nuclei and reduced amount of gas required for forming gaseous cavitation nuclei. |
