The conductometric method based on the measurement of electrical conductivity of the gas-liquid-liquid system was used to evaluate the flow patterns. In the studies, a set of eight probes spaced concentrically in two tube sections (four probes per each) with a spacing of 0.015 m were used. The paper presents a theoretical description of the test method and the analysis of the measurement results for air-oil-water multiphase flow system. Results of this study indicate that the developed method of characterizing the voltage of the gas-liquid-liquid system can be an important tool supporting other methods to identify flow patterns, including visual observation.}, type={Artykuły / Articles}, title={A conductometric method for determining of the upward gas-liquid-liquid three-phase flow}, URL={http://journals.pan.pl/Content/109071/PDF/07_paper.pdf}, keywords={conductometric method, three-phase flow, flow patterns}, }
