... 1 ABSTRACT Three phase flow system instabilities have recently been investigated in a 3" flowline-riser medium scale model system at the Equinor Porsgrunn test facilities in Norway. The test setup is well instrumented and comprises an 87 [m] long horizontal flowline followed by a 13 [m] high C...

... to their wear resistance in multiphase environments. It will be shown how parameters such as the flow velocities, temperature, electrochemical potentials and different oil/water cuts can be investigated and how different materials perform under these conditions. The main objective of the paper is to illustrate...

... and show that the phenomenon under investigation is more complex than expected. In particular it has been found that for large liquid viscosity, the bubble drift velocity decreases along the pipe. This result, which can be easily justified on a theoretical ground, poses some clear limitations to the use...
