Séminaire PMMH – Christiana Mavroyiakoumou (Oxford University)
Sail dynamics during tacking maneuvers
Tacking is a sailing maneuver that is necessary for upwind navigation. In this talk, I will introduce a sail membrane and vortex–sheet model, used to systematically characterize how a wide range of sail material parameters and tacking motions affects the sail dynamics during a tacking maneuver. I will focus on whether a given set of parameters will result in a “successful tack,” meaning that the sail will flip around to adopt its mirror-image shape, or if it will remain stuck in a metastable state that is close to its initial shape. I will also talk about slack sails and show that they are more difficult to flip.

The audience is composed of people with rather heterogeneous backgrounds including specialists in solids, fluids, granular flows, statistical physics... so the idea is to keep your talk understandable by people not necessarily working in your field... The seminar time slot runs from 11am to noon so the best is to make the talk last around 45 minutes to leave some time for discussion.
