Quelques aspects de l'écoulement potentiel autour d'un corps en rotation

On the basis of simple conformal mappings, we present a method to describe a two-dimensional potential flow around a rotating obstacle of arbitrary section. As a result, a simplified expression of the matrix of added mass and added moment of inertia is obtained. We also underline the need to determine this perturbation potential all over the fluid domain. Indeed, this is of practical interest in order to express the hydrodynamic moment in incompressible viscous flow. To cite this article: Y.-M. Scolan, C. R. Mecanique 333 (2005).
