It is well-known that laminar flow of a liquid in a duct is predicted to choke if the viscosity of the liquid increases exponentially with increasing pressure. In other words, the pressure drop in the duct is predicted to become unbounded when the volumetric flow rate reaches a critical finite value. Choking is not observed in practice, however: the reason why is investigated here. It is shown ...

Severe slugging is an unstable multiphase flow pattern occurs in a pipeline riser with low gas and liquid flowrates. It highly undesired practical operation because of the pressure mass oscillations induced. Riser outlet choking has shown effectiveness eliminating or reducing severity slugging. This work presents experimental numerical study on elimination severe riser-induced slug by means cho...

C i c ^ A one-dimensional theory based upon fundamental flow relationships ^ is presented for analyzing the behavior of one or more gas streams flowing MM through a single nozzle. This conpound-coropressible flow theory shows that f^ the behavior of each stream is influenced by the presence of the other ^^ streams. The theory also shows that the behavior of coiTpound--coiTpressible flow is pred...
