Geometrically Templated Dynamic Wrinkling from Suspended Poly(vinyl alcohol) Soap Films
Yuchong Gao, Yinding Chi, Mohit Patel +4
Wrinkling is commonly observed as mechanical instability when a stiff thin film bound on a compliant thick substrate undergoes in-plane compression exceeding a threshold. Despite s…
Gravity-driven coatings on curved substrates: a differential geometry approach
Pier Giuseppe Ledda, Matteo Pezzulla, Etienne Jambon-Puillet +2
Although the drainage and spreading processes of thin liquid films on substrates have received growing attention during the last decades, the study of three-dimensional cases is li…
Particle size selection in capillary instability of locally heated co-axial fiber
Saviz Mowlavi, Isha Shukla, PT Brun +1
Harnessing fluidic instabilities to produce structures with robust and regular properties has recently emerged as a new fabrication paradigm. This is exemplified in the work of Gum…
Curvature regularization near contacts with stretched elastic tubes
Bhargav Rallabandi, Joel Marthelot, P. -T. Brun +1
Bringing a rigid object into contact with a soft elastic tube causes the tube to conform to the surface of the object, resulting in contact lines. The curvature of the tube walls n…
Oscillations of confined fibers transported in microchannels
Mathias Nagel, Pierre-Thomas Brun, Helene Berthet +3
We investigate the trajectories of rigid fibers as they are transported in a pressure-driven flow, at low Reynolds number, in shallow Hele Shaw cells. The transverse confinement an…
The surprising dynamics of a chain on a pulley: Lift-off and snapping
Pierre-Thomas Brun, Basile Audoly, Alain Goriely +1
The motion of weights attached to a chain or string moving on a frictionless pulley is a classic problem of introductory physics used to understand the relationship between force a…
Liquid ropes: a geometrical model for thin viscous jets instabilities
P. -T. Brun, Basile Audoly, Neil M. Ribe +2
Thin viscous fluid threads falling onto a moving belt behave in a way reminiscent of a sewing machine, generating a rich variety of periodic stitch-like patterns including meanders…
A discrete geometric approach for simulating the dynamics of thin viscous threads
Basile Audoly, Nicolas Clauvelin, Pierre-Thomas Brun +3
We present a numerical model for the dynamics of thin viscous threads based on a discrete, Lagrangian formulation of the smooth equations. The model makes use of a condensed set of…
A numerical investigation of the fluid mechanical sewing machine
Pierre-Thomas Brun, Neil M. Ribe, Basile Audoly
A thin thread of viscous fluid falling onto a moving belt generates a surprising variety of patterns depending on the belt speed, fall height, flow rate, and fluid properties. Here…
