It was recently demonstrated that feeding a silicon-in-silica coaxial fibre into a flame$\mathord{-}$imparting a steep silica viscosity gradient$\mathord{-}$results in the formation of silicon spheres whose size is controlled by the feed speed [Gumen

Linear stability analysis of capillary instabilities for concentric cylindrical shells

Autor: Liang, X., Deng, D. S., Nave, J. -C., Johnson, S. G.

Publikováno v: Journal of Fluid Mechanics, 2011

Motivated by complex multi-fluid geometries currently being explored in fibre-device manufacturing, we study capillary instabilities in concentric cylindrical flows of $N$ fluids with arbitrary viscosities, thicknesses, densities, and surface tension

Capillary instability in concentric-cylindrical shell: numerical simulation and applications in composite microstructured fibers

Autor: Deng, D. S., Nave, J. -C., Liang, X., Johnson, S. G., Fink, Y.

Publikováno v: Optics Express, Vol. 19, Issue 17, pp. 16273-16290 (2011)

Recent experimental observations have demonstrated interesting instability phenomenon during thermal drawing of microstructured glass/polymer fibers, and these observations motivate us to examine surface-tension-driven instabilities in concentric cyl
