We combine analytical, numerical, and experimental approaches to study the dynamics of the ‘liquid rope coiling’ that occurs when a thin stream of viscous fluid like honey falls onto a surface. As the fall height increases, coiling traverses a sequence of four dynamical regimes (viscous, gravitational, inertio-gravitational, and inertial) characterized by different balances of the forces acting on the rope. The inertio-gravitational regime is particularly rich, exhibiting multiple states that correspond to resonant modes of the rope’s ‘tail’. Résumé: Nous étudions avec des méthodes analytique, numérique et expérimentale le flambage hélicoïdal d’un mince filet de fluide visqueux (e.g., miel) qui tombe sur une surface. Lorsque la hauteur de c...
