Abstract
This article explores the formation of spiral vortex and application of liquid aerators. Visually, the new method has been applied for three structures of the stream ejector. The paper shows that under the same traffic flow, the venturi tube with blade cup liquid creates maximum ejected liquid contact surface. It has been noticed that the flared shape of the ejector blade that is close to the form of the spiral vortex, creates improvements in a pulsation flow and thus increases the solubility of oxygen in the liquid. Santrauka Straipsnyje tyrinėjamas spiralinio sūkurio formavimas ir taikymas skysčio aeratoriuose. Vizualiniu metodu išbandytos trys naujos srautinių čiurkšlinių siurblių konstrukcijos. Parodyta, kad čiurkšliniu siurbliu su menteliniu skysčio užsukimu, esant tam pačiam darbinio srauto debitui, sukuriamas didžiausias siurbiamo skysčio sąlyčio paviršius. Pastebėta, kad mentelinio čiurkšlinio siurblio fakelo forma artima spiralinio sūkurio formai, kuri sukuria srauto pulsacijas, pagerinančias deguonies tirpumą skystyje.
