Abstract

Zaključna naloga obravnava karakterizacijo struktur dvofaznega toka pri razpadu curka plina v prečnem toku kapljevine. Izdelan je bil merilnik za detekcijo plina oz. kapljevine na osnovi sipanja laserske svetlobe. Testiranje je potekalo na obstoječem preizkuševališču. Zasnovan je bil algoritem za prepoznavanje režima tvorjenja mehurčkov na podlagi podatkov, pridobljenih z merilnikom. Narejene so bile meritve pri različnih kombinacijah pretokov zraka in vode. Izvedena je bila prepoznava različnih režimov tvorjenja mehurčkov, ki smo jih delili na tri glavne režime: posamični mehurčki, pulzirajoči mehurčki in curek. Rezultati so bili primerjani z analizo posnetkov s hitro kamero.

Secondary title: Experimental evaluation of two-phase flow structures at the gas jet breakup in a liquid cross-flow
Secondary abstract: The thesis deals with the characterization of two-phase flow structures at the gas jet breakup in a liquid cross-flow. A phase detection instrument based on laser light scattering was developed. Tests were performed on the existing test section. An algorithm was designed to identify the bubble formation regime based on the data obtained by the developed instrument. Measurements were carried out at different combinations of air and water flows. Different bubble formation regimes were identified, which were divided into three main regimes: single bubbling, pulse bubbling, and jetting. The results were compared with the high-speed camera analysis.
