International ClassB05B 007/06AbstractIn the field of jet technology a nozzle of a liquid-gas jet apparatus for feed of an active liquid medium has a central channel and a peripheral annular channel and the total surface area of the outlet cross-section of the nozzle channels is determined from the following formula: S=Sμ (1+(Skc /Sμ)3), where S--is the total surface area of the outlet cross-section of the nozzle; Sμ --is the surface area of the outlet cross-section of the central channel of the nozzle; and Skc --is the surface area of the minimal cross-section of the mixing chamber. A liquid-gas jet apparatus with the above-mentioned features has a higher efficiency and an improved reliability.Field of SearchCOMBINING OF SEPARATELY SUPPLIED FLUIDS (I.E., PLURAL FLOW PATHS)At or beyond outlet Induction of ambient air Concurrent or concentric flow means Flow means of one fluid surrounds the other at outlet Ambient air aspirated through inner flow path Getter heating, vaporizing, or regeneration Of pumping one fluid by contact or entrainment with another Plural motive fluid jets or sources for single entrainment Specific material Expressed mathematically or dimensionally Specific motive fluid nozzle | |
