In order to move forward in the fundamental knowledge of the behavior of three-phase flows, new experimental data has been obtained in a facility specially designed for flow visualization and for measuring key parameters. These are (1) the flow regime, (2) the superficial velocities or rates of the individual phases; and (3) the frictional pressure loss. Flow visualization and pressure measurements are performed for two and three-phase flows in horizontal 30 mm inner diameter and 4.5 m long transparent acrylic pipes. A total of 134 flow conditions are analyzed and presented, including plug and slug flows in air–water two-phase flows and air–water-polypropylene (pellets) three-phase flows. For two-phase flows the transition from plug to slug flow agrees with the flow regime maps available in the literature. However, for three phase flows, a progressive displacement towards higher gas superficial velocities is found as the solid concentration is increased. The performance of a modified Lockhart–Martinelli correlation is tested for predicting frictional pressure gradient of three-phase flows with solid particles less dense than the liquid. info:eu-repo/grantAgreement/EC/H2020/713679/EU/Martí i Franquès COFUND/MFP This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 713679-MFP info:eu-repo/grantAgreement/ES/MINECO/DPI2016-75791-C2-2-P/1-P info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.305 2020 THERMODYNAMICS 32 / 60 = 0.533 2020 Q3 T2 MECHANICS 70 / 135 = 0.519 2020 Q3 T2 0.738 2020 Chemical Engineering (miscellaneous) 2020 Q1 Physics and Astronomy (miscellaneous) 2020 Q1 Physical and Theoretical Chemistry 2020 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Stiriba, Youssef Lobera, Julia Universidad de Zaragoza (orcid)0000-0001-7930-272X Palero, Virginia Universidad de Zaragoza (orcid)0000-0003-1955-6714 Pallarès, Jordi 2002 385 Universidad de Zaragoza Dpto.
