Summary
Even at constant inlet and outlet boundary conditions (represented by gas
and liquid mass flow rates and separator pressure, respectively),
unsteady-state flow may occur in a pipeline/riser system operating at
relatively low gas and liquid flow rates. The cyclic unsteady-state flow
characterized by large-amplitude pressure and flow rate fluctuations has been
referred to as severe slugging. This study is an experimental investigation of
flow instabilities, especially severe slugging, in a relatively long
hilly-terrain pipeline/ riser system. Five types of flow regimes were found and
characterized on the basis of visual observation and the measured pressure drop
over the riser.
