Experimental investigation of the development of surfactant stabilized oil-water pipe flow downstream of a choke valve
Schümann, Heiner; Simonsen, Galina; Brekken, Christian (Peer reviewed; Journal article, 2023)In wells and multiphase flowlines the presence of valves, pumps and other complex geometries will considerable contribute to dispersion of the phases. In combination with the droplet stabilizing effect of natural surfactants ... -
Pseudo slug flow in viscous oil systems – experiments and modelling with LedaFlow
Kjølaas, Jørn; Smith, Ivar Eskerud; Brekken, Christian (11th North American Conference on Multiphase Technology;2018, Chapter; Peer reviewed, 2018)An experimental two-phase flow campaign with a viscous oil (100 cP) was conducted in the Large Scale 8" loop at the SINTEF Multiphase Flow Laboratory. The loop consisted of three main test sections, with pipe inclinations ... -
Repeatability in a multiphase pipe flow case study
Strand, Andreas; Brekken, Christian; Leinan, Paul Roger; Steinsland, Ingelin; Hellevik, Leif Rune (Peer reviewed; Journal article, 2021)A high degree of repeatability is most often an underlying assumption for research and development based on multiphase flow experiments. In this paper repeatability in multiphase flow experiments are studied through an ... -
Simulation of two-phase viscous oil flow
Johansen, Stein Tore; Mo, Sjur; Kjølaas, Jørn; Brekken, Christian; Smith, Eskerud (SINTEF Proceedings;1, Chapter; Conference object; Peer reviewed, 2015)Multiphase flows of heavy oils and other fluids with high apparent viscosity is a particular industrial challenge. Main challenges here is that interfacial waves, atomization at the large scale gas–liquid interface as well ...
