Influence of Pulsating Internal flow on Marine Riser with Nonlinear Geometry

Résumé

In this work, we numerically explore the dynamics of inclined marine risers subjected to pulsating internal fluid flow. The presence of geometric nonlinearities with static deflection makes the response of the inclined riser different from conventional top tension risers when subjected to pulsating flows. The riser model is solved via Galerkin method and validated using perturbation approaches for single mode. Then, we study the multi-modal dynamic response of the riser which reveals interesting and complex nonlinear interactions.
