Complex Orthogonal Decomposition (C.O.D.) using Python
Marc Vacher, Stéphane Perrard, Sophie Ramananarivo
This work presents the application of the Complex Orthogonal Decomposition (C.O.D.) to a simple spatio-temporal signal. C.O.D. has been introduced rst in the article of B. Feeny, e…
Three-dimensional flow around and through a porous screen
Olivier C. Marchand, Sophie Ramananarivo, Camille Duprat +1
We investigate the three-dimensional flow around and through a porous screen for various porosities at high Reynolds number Re = O(10000). Historically, the study of this problem w…
Paragliders' Launch Trajectory is Universal
Quentin Da Cruz Lopes, Sophie Ramananarivo, Caroline Cohen +1
We designed and built a reduced-scale model experiment to study the paragliding inflation and launching phase at given traction force. We show that the launch trajectory of a singl…
Activity-controlled Annealing of Colloidal Monolayers
Sophie Ramananarivo, Etienne Ducrot, Jeremie Palacci
Molecular motors are essential to the living, they generate additional fluctuations that boost transport and assist assembly. Self-propelled colloids, that consume energy to move,…
Elastic swimmer on a free surface
Sophie Ramananarivo, Benjamin Thiria, Ramiro Godoy-Diana
We present in this fluid dynamics video a novel experimental setup with self-propelled swimmers on a free surface. The swimmers, modeled as flexible thin filaments, are subjected t…
Rather than resonance, flapping wing flyers may play on aerodynamics to improve performance
Sophie Ramananarivo, Ramiro Godoy-Diana, Benjamin Thiria
Saving energy and enhancing performance are secular preoccupations shared by both nature and human beings. In animal locomotion, flapping flyers or swimmers rely on the flexibility…
