Interactions between flow and actuated structures simulated through a Vortex Particle-Mesh method : application to swimming and energy harvesting devices
European eels (Anguilla anguilla) undertake a 5000-km spawning migration from Europe to the Sargasso Sea although they do not feed during the migration. Indeed swimming organisms at large have refined their senses, morphologies, gaits and mechanical properties to effectively propel and maneuver in a...

European eels (Anguilla anguilla) undertake a 5000-km spawning migration from Europe to the Sargasso Sea although they do not feed during the migration. Indeed swimming organisms at large have refined their senses, morphologies, gaits and mechanical properties to effectively propel and maneuver in a variety of unsteady flow conditions. The understanding of new design paradigms that exploit flow induced mechanical instabilities for propulsion or energy harvesting demands robust and accurate flow structure interaction numerical models. In this context, we develop a novel two dimensional algorithm that combines a Vortex Particle-Mesh (VPM) method and a Multi-Body System (MBS) solver for the simulation of passive and actuated structures in fluids. This method further captures dynamic interactions between the fluid and articulated structures that can be either discontinuous or continuous.
