Stand Nage de micro-organismes: fluides visqueux et réversibilité temporelle
Stefano Berti and Enrico Calzavarini
Micro-organisms feel ordinary fluids like water the same way macroscopic organisms feel very viscous ones. This means that, at micron scales, swimming takes place in a low-Reynolds-number medium. In such environments, to achieve propulsion it is necessary to break time reversibility and this implies that not all sequences of elementary movements allow to swim. By realising simple macroscopic experiments in very viscous fluids we discuss some common swimming strategies adopted by micro-organisms.
