AbstractThis paper presents a two-dimensional parametric analysis of the influence of an internal slug flow on thestructural dynamic response of flexible risers. The parametric analysis allow us to study the behaviour of theparametersinvolvedinthedynamicresponseofflexibleriserswithaninternalslugflow,suchasdisplacements,top tension, and bending moment, when any of the parameters characterizing the slug flow is modified. Toaccomplishthisgoal,acomputationaltoolisdeveloped.Thespatialdiscretizationoftheriserisperformedusingbeam finite elements and the corotational approach is used for the two-dimensional formulation of the beamelement. The beam elements have a linear elastic behaviour and they are submitted to large displacements,althoughwithsmalldeformations.Theincremental-iterativeNewton-Raphsonschemeforfollowerloadsisusedto solve the equilibrium equations in dynamic analysis. Time domain numerical integration is performed usingtheconstantaverageaccelerationmethod.Theslugflowisviewedasasingle-phasefluidwithvariabledensity,which is modelled by a periodic function. The numerical results show good coherence when compared to theexperimental ones, qualifying the computational tool to conduct parametric studies about dynamic of flexiblemarine risers with an internal slug flow.
