SUMMARY:Séminaire du LPTMS: Neil Ribe - LPTMS\, salle 201\, 2ème étage\,
  Bât 100\, Campus d'Orsay - 22 Mar 16 11:00
DESCRIPTION:Acrobatics of liquid ropes\nNeil Ribe (FAST\, Université Paris
 -Sud)\nA thin `rope' of viscous fluid falling from a sufficient height ont
 o a surface forms a steadily rotating helical coil. Tabletop laboratory ex
 periments in combination with a numerical model for slender fluid ropes re
 veal that finite-amplitude coiling can occur in four distinct regimes (vis
 cous\, gravitational\, inertio-gravitational\, and inertial) corresponding
  to different balances among the three principal forces acting on the rope
 . The model further shows that the onset of coiling has distinct viscous\,
  gravitational and inertial modes that connect smoothly with the correspon
 ding finite-amplitude regimes. I will also discuss some striking examples 
 of non-stationary behavior of liquid ropes\, including propagating spiral 
 waves of air bubbles\, supercoiling\, and the `fluid mechanical sewing mac
 hine' wherein the rope leaves complex `stitch' patterns on a moving surfac
 e.
