[Développement d’une méthode de calcul de la dérive des objet flottants en mer basée sur l’utilisation de polaires]
La localisation des objets flottants et des personnes à la dérive est une part importante des missions de sauvetage en mer, il est dès lors important de disposer d’outils efficaces pour déterminer la trajectoire de tels objets. La méthode actuellement employée présente certaines limitations et peut s’avérer imprécise. Le développement d’une nouvelle méthode basée sur l’utilisation de polaires de coefficients aérodynamiques calculés à l’aide d’outils de mécanique des fluides numérique est considéré en tant qu’alternative. Cette approche est mise en œuvre pour un conteneur standard. Ces premiers résultats bien que perfectibles semblent prometteurs et témoignent du potentiel de cette approche.
Localisation of drifting objects and lost at sea persons is an integral part of search and rescue (SAR) missions. It is thus important to possess effective tools to determine the trajectory of such objects. The method currently used presents some limitations and may prove imprecise in certain cases. The development of a new method based on CFD-generated drag and lift polars is therefore investigated as an alternative. This approach is implemented in a simplified manner for a 40-feet container, and the results compared to the method currently in use. These results, though improvable, appear promising and prove the potential of this approach.
