Abstract
From an experimental campaign planned to study the dynamics of flexible pipes aspirating water under vortex-induced vibrations (VIV), carried out in the towing tank facilities at the Institute for Technological Research (IPT) - São Paulo, Brazil, this work brings a preliminary theoretical-experimental comparison. Numerical simulations, performed both with an in-house mathematical model and with a commercial software package (Orcaflex™), are performed to assess experimental scenarios. In a general agreement with the experimental results, the numerical analyses reveal that the influence of aspirating internal flow on VIV is marginal, even in a post-critical condition. The numerical models, however, were not able to fully recover the complex dynamics observed in the experiments, even though the in-house model presented better adherence to the experimental analysis.
