Severe slug flow (i.e., terrain-dominated slug flow) was studied in a simulated offshore pipeline riser-pipe system. Severe slug flow is characterized by extremely long liquid slugs generated at the base of the vertical riser. This phenomenon occurs at low gas and liquid flow rates and for negative pipeline inclinations. Slugging in …

Webb1 nov. 2012 · Severe slugging is a transient cyclic phenomenon which may occur in multiphase pipeline–riser systems. At relatively low flow rates, liquid accumulates at the riser base, creating a blockage for the gas, until sufficient upstream pressure has been built up to flush the liquid slug out of the riser.
