Séminaire PMMH - Patrick Bot (Institut de Recherche de l’Ecole Navale)
From sails aerodynamics to the Lift Crisis (and other results on the lift generated by a highly curved plate)
Yacht sails show some peculiarities among aerodynamic systems. Rather flat sails are used to sail upwind, and the flow remains mostly attached. To sail downwind, highly cambered sails may be used where flow separation is significant. Some results will be shown on the flow around a spinnaker and the related fluid structure interaction, both from full-scale testing on the water and model-scale testing in a wind tunnel. To focus on the flow and make the system more simple to investigate, we tested in a water channel a 2D rigid highly cambered section (a curved plate) and found a few original behaviors of this high-lift and not-so-slender body.
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.
