Abstract: In this paper the results of the numerical modeling of two-phase gas and liquid flows are given in horizontal channels for the purpose of definition of occurring flow structures and their existence conditions. The calculations were performed for two-dimensional models. The regimes occurring at the velocity range from 0.1 m/s to 15 m/s and various phase relation were under investigation. The phase boundaries location in the flow was determined with the VOF- volume of fluid method. The discovered flow structures were qualitatively analyzed and identified due to the accepted classification. Parameters of the modeling regimes were compared to the semi-empirical regime map of Taitel and Dukler, whereby the expected flow type was determined. The area of stream structures coincidence was defined in the numerical modeling using the regime map of Taitel and Dukler.
