Análise crítica de um modelo fenomenológico de vibrações induzidas por vórtices via análise de sensibilidade global e quantificação de incertezas
The phenomenon of vortex-induced vibrations (VIV) is investigated in the present Dissertation. These vibrations are the result of the intricate fluid-structure interaction between the body and its external flow, being undesirable in the offshore industry. Therefore, phenomenological models continue …

Equilíbrio e vibrações induzidas por vórtices de "risers" de perfuração
Presents a study about drilling risers used by semisubmersible platforms in order to drill wells in deep waters. Firstly, a study about static equilibrium is presented. This allows to select adequate risers for places with usual natural conditions. The selection takes into account the riser …
