Asymmetric instability in thin-film flow down a fiber
Chase T. Gabbard, Joshua B. Bostwick
Abstract
Experiments show that thin film flow down a fiber exhibits beading patterns whose symmetry about the fiber depends upon the fiber diameter and liquid surface tension. Both symmetric and asymmetric morphologies exhibit absolute (isolated, Plateau-Rayleigh) and convective instabilities, with the asymmetric beading dynamics resembling that of the free viscous jet indicating a minimal interaction between the liquid and fiber.
