Numerical modelling of the interaction between severe slugging and dynamic response of deepwater risers: A time-domain ANHE-FD based solution

Severe slugging in deepwater risers is a serious flow assurance problem that endangers the reliability of subsea production systems (pipelines, risers, and jumpers) by exposing them to fatigue loading, structural instability, and material damage due to its cyclic behaviour. Modelling this problem is very challenging because of its nonlinearity and the need to establish a coupled fluid–structure interaction (FSI) model that will reflect the...
