Undulatory underwater swimming: Linking vortex dynamics, thrust, and wake structure with a biorobotic fish
Christophe Brouzet, Christophe Raufaste, Médéric Argentina
Flapping-based propulsive systems rely on fluid-structure interactions to produce thrust. At intermediate and high Reynolds numbers, vortex formation and organization in the wake o…
Optimum control strategies for maximum thrust production in underwater undulatory swimming
L. fu, S. Israilov, J. Sanchez Rodriguez +4
Fishes, cetaceans, and many other aquatic vertebrates undulate their bodies to propel themselves through water. Swimming requires an intricate interplay between sensing the environ…
Scaling the tail beat frequency and swimming speed in underwater undulatory swimming
Jesús Sánchez-Rodríguez, Christophe Raufaste, Mederic Argentina
Due to its great efficiency and maneuverability, undulatory swimming is the predominant form of locomotion in aquatic vertebrates. A myriad of animals of different species and size…
Curvature-driven transport of thin Bingham fluid layers in airway bifurcations
Cyril Karamaoun, Haribalan Kumar, Médéric Argentina +2
The mucus on the bronchial wall forms a thin layer of non-Newtonian fluid. One of the roles of mucus is to protect the lungs by capturing inhaled pollutants. It is transported by m…
Dynamics of elastically strained islands in presence of an anisotropic surface energy
Guido Schifani, Médéric Argentina, Thomas Frisch
The equilibrium solutions and coarsening dynamics of strained semi-conductor islands are investigated analytically and numerically. We develop an analytical model to study the effe…
Shape and coarsening dynamics of strained islands
Guido Schifani, Thomas Frisch, Mederic Argentina +1
We investigate the formation and the coarsening dynamics of islands in a strained epitaxial semi-conductor film. These islands are commonly observed in thin films undergoing a morp…
Wave-train induced unpinning of weakly anchored vortices in excitable media
Alain Pumir, Sitabhra Sinha, S. Sridhar +6
A free vortex in excitable media can be displaced and removed by a wave-train. However, simple physical arguments suggest that vortices anchored to large inexcitable obstacles cann…
Interface dynamics in shear-banding flow of giant micelles
S. Lerouge, M. A. Fardin, M. Argentina +2
We report on a non trivial dynamics of the interface between shear bands following a start-up of flow in a semi-dilute wormlike micellar system investigated using a combination of…
