... ABSTRACT The Gannet oil export pipeline is operating at relatively low flow rates. At these low flow rates, there is potential to have a flow regime with laminar flow instead of with turbulent flow. Therefore, the viscosity, or rather the rheological properties, of this oil are essential...

..., the flow regime was slug flow and it was found that there are errors of 48 and 25% in the CFD predictions for Newtonian and non- Newtonian liquids, respectively. Another drawback that can be inferred from the review of available studies is that the range of velocities employed is limited to lower...

... with the turbulent field of the gas flow. Introduction Stratified gas/liquid flow is a flow regime that is often in industries such as petroleum, chemical processing and nuclear. This specific flow regime occurs when the flow rate of each phase is low enough, i.e. below the onset of intermittent flows...
