Abstract

V predstavljenem delu je bil eksperimentalno obravnavan in analiziran dvofazni tok v vzgonskem reaktorju. Postavljena je bila eksperimentalna kolona, kjer smo lahko zajemali podatke o pretoku tekočin in padcu tlaka. Določali smo volumski delež plina in zajeli posnetke s hitro kamero. Ugotovitve smo primerjali z numeričnim modelom iz literature. Strukture in obratovalne režime dvofaznega toka smo uspeli razlikovati s pomočjo frekvenčne analize tlačnih nihanj. Rezultati so bili skladni z video analizo.

Secondary title: Experimental evaluation of gas-liquid two-phase flow in an airlift reactor
Secondary abstract: The topic of this thesis is the experimental analysis of two-phase flow in an airlift reactor. For this purpose, an experimental rig was set up in which measurements of volume flow and pressure drop were performed. The gas holdup was measured and the flow was observed with a high speed camera. The results were compared with a numerical model from the literature. We were able to distinguish two-phase flow structures and operating modes by spectral analysis of the differential pressure signal. The results were consistent with the video analysis.
